Unfortunately he’s never really gotten off the mark in England. He’s been very poor overall and needs the fresh start he should get in Germany. Also, worth noting that Whoscored reports him at 185cm and 87kg. I don’t really know metric stuff, but he seems bigger than 79kg.
As for stat suggestions:
Attack: 78 -> 76
Defence: 34 -> 36 works pretty well in this aspect and drops deep to assist or covering the wings when he’s out wide
Stamina: 74 -> 76 he gets tired and subbed, but lasts enough to be worth low green
Top Speed: 81 -> 79 he’s slower as well on the top end
Acceleration: 77 -> 74 this is the bigger drop as he shifts gears like a person just starting to learn to drive stick
Agility: 79 -> 73 he’s bulked up a good bit and his agility is far worse for it
Dribble Accuracy: 77 -> 75 much sloppier with the ball at his feet
Dribble Speed: 78 -> 75 can’t progress at speed or pull of many trick. Could be the playing weight, but after looking at a few clips from his PSV days it’s just a skill that’s diminished
Short Pass Accuracy: 76 -> 74 less accurate than before. He has a good eye for incisive passes, but they’re very simple and when it’s a tight angle he sees he either passes up the chance or gives it away
Long Pass Speed: 74 -> 72 float quite a bit when more driven passes would result in assists
Shot Accuracy: 82 -> 76 his shots are at the keeper or off target. Once or twice he’s been unlucky, but not really anything ever in England to show he’s a good shooter
Shot Technique: 80 -> 75 he can make contact and occasionally keep it on target, but he’s just not going to do it at the requisite level. Too many go skyward or sharply cutting out of danger
Technique: 80 -> 75 his touch let’s him down a lot as the ball pops up from his foot and combined with his decreased speed and agility lead him into situations where he is pressed and trapped
It feels a bit like he’s gotten too big for his own good. He’s not the target man of the team and when asked to do the technical stuff with more than one touch linkup play, which he’s still solid at, he is going to struggle. Hoffenheim should be a good place for him to regroup since the depth at Brighton is going to be hard to crack now. Still some salvageable parts of his game, but 2 goals in 1200 minutes last season are far from an indication of a player performing up to standard.
