Hello again, football fans! I hope everyone’s had an enjoyable holidays, and are ready for the second half of the season in Europe! As we are pretty much at the halfway point for Europe’s top 5 leagues, I thought I’d start a series looking at the top players from each position based on performance this season alone! Today’s article will be the keepers, and there are certainly some standouts to discuss, none more so than this articles headliner: Alvaro Valles.
Álvaro Valles (La Liga/ Las Palmas,/26 years old)

For me, the award of “Most Valuable Keeper” so far this season can only go to one man. Álvaro Valles is performing so much better than any other keeper could be expected to in his place, it is almost unbelievable. Playing for a newly promoted Las Palmas side in La Liga, Valles has accumulated a mind-blowing 10.3 Goals Prevented so far this season across 18 matches.
Goals Prevented and xG on Target (xGoT):
Goals Prevented is an advanced statistic that compares the total xGoT (xG on Target) a keeper has faced to the number of goals conceded. Most of you have probably heard of xG by now, but perhaps not xGoT. While xG is a measure of the quality of shot selection (location of shot, # of nearby defenders, type of shot), xGoT is a measure of the quality of the actual shot taken. The most obvious example to use is someone like Roberto Carlos, known for his powerful and accurate free kicks. The xG given to a Roberto Carlos free kick would be very low, because it is based on an average of all shots taken by all footballers in that league over time (let’s say the xG = 0.05). Now let’s say Roberto Carlos takes the free kick, and it is perfectly struck right into the top corner, off the post and in. The xGoT attributed to this shot would be very high, much higher than the initial xG, due to the quality of Carlos’s shot. This is why we use xGoT when analysing keepers, not xG. To summarize, “Goals Prevented” is the difference between all of the xGoT accumulated on a keeper, and that keeper’s goals conceded.
Now, back to Valles. Valles has a Goals Prevented total this year of 10.3 so far, meaning based on the quality of shots he has faced, we would expect at least 10 more goals to have been conceded by Valles. To put this stat into context, the next best in La Liga is Unai Simon, with 4 Goals Prevented, while the Premier League’s leader, Thomas Kaminski, has 5.0 Goals Prevented, less than half that of Valles! Las Palmas, as a newly promoted side, have the 2nd fewest goals conceded in La Liga after only Real Madrid, and Alvaro Valles is the biggest reason why. Las Palmas currently sit 9th in La Liga at the time of writing, and one has to expect them to stay mid-table if they can hold on to Valles, which may not be a sure thing. Barcelona are reportedly already looking at buying Valles from Las Palmas, which would make sense from their perspective.
Thomas Kaminski (Premier League/Luton Town/ 31 years old)

After making 118 appearances for Blackburn from 2020-2023, Thomas Kaminski signed with Luton Town ahead of their inaugural Premier League season. Since joining, he has been outstanding for the Hatters, seemingly giving them a chance in every game despite not having nearly as much talent in the squad as the rest of the league. This is reflected in the fact that Luton are 3rd worst in the Premier League in goals conceded this year, and yet Kaminski is still outperforming expectations, with 5.0 Goals Prevented this season. With Luton currently sitting one win from pulling themselves out of the relegation zone, there will be one main person to thank if they stay up this year, Thomas Kaminski. His performances against the best clubs in the league have been quite admirable , making 5 stops to earn a draw vs Liverpool, while outperforming his expected goals conceded in near every match Luton play.
Marcin Bulka (Ligue 1/OGC Nice/24 years old)

Undoubtedly the top keeper in Ligue 1 this season, and a major part in Nice sitting just 5 points off league leaders PSG by New Year’s, the Polish former Chelsea academy keeper is truly making a name for himself this season. 17 matches played, 11 clean sheets. Yes, you read that correctly. Bulka has recorded a clean sheet in 65% of Nice’s Ligue 1 matches this season, and Nice’s 9 goals conceded so far is the lowest in Ligue 1, 5 less than next best PSG and Lille. Bulka boasts the highest save percentage in Ligue 1, as well as a very respectable 4.0 Goals Prevented. Bulka has saved 2/3 of the penalties he’s faced this year, and looks to become one of the transfer market’s most wanted keepers if he can continue this form. At only 24 years old, the sky is very much still the limit for Bulka and I wouldn’t be surprised if he’s moved on from Nice in a year’s time.
Guglielmo Vicario (Premier League/Spurs/27 years old)

Throughout last season, it became a sad truth to Spurs that their longtime leader in net, Hugo Lloris, was clearly past his prime and could no longer offer what is needed from a modern goalkeeper, especially with the ball at his feet and acting as a sweeper. Enter Guglielmo Vicario, fresh off a career season at Empoli where he was the main reason that Empoli did not get relegated (see: this year’s Serie A table), arriving at Spurs for a 18.5 million euro fee. Vicario wasted no time upon arriving, establishing himself as the clear #1 keeper of the future and showing how perfectly suited he was to play under Ange Postecoglu’s new system at Spurs. If there were any doubts about Vicario’s sweeping ability before this year, I’d like to turn your attention to the Chelsea 4-1 Spurs result from this year. In this match, Spurs went down to 9 men and played an extremely high line despite the disadvantage, often at the midfield line. Countless times Vicario sprung out of his box to clear a through ball sent in behind the Spurs’ backline, and he alone prevented the scoreline from being something closer to 8-1. Having watched every Spurs game so far this year, I have yet to see a bad performance from Vicario, he has been without a doubt Tottenham’s most consistent player this season, offering so much calmness and composure at the back. Even when his teammate makes a mistake, Vicario is quick to tell them to shake it off and move on, unlike many keepers we see who seem to love any opportunity to scream at their defence whenever they make a save. From his ball playing ability, to his shot stopping, to his mentality and leadership, Guglielmo Vicario has been a perfect signing for Spurs, and will be one of the Premier League’s top keepers for years to come.
Honorable Mentions: Lukas Hradecky (Leverkusen), Marvin Schwabe (Koln), Michele Di Gregorio (Monza), Yann Sommer (Inter), Brice Samba (Lens)
Conclusion:
So that wraps up my top performers in goal so far this season! How many of these keepers will remain on their team in a year’s time, and how many will be picked up by bigger clubs? By just how much will Alvaro Valles finish the season as the best keeper in La Liga? Will Thomas Kaminski or Guglielmo Vicario finish the year with the most Goals Prevented in the Premier League? We’ll have to wait and see to find out the answers to these questions, but that’s the fun of football isn’t it? Thanks to everyone for reading, and as always feel free to leave any comments or suggestions!
