You can't judge a player after only 1 game. The first game I've seen him playing was in 2008, when he was 15 years old and he came on as a substitute in Slovenian first league. Domžale (his club than), referee and few other people were fined, as he was ineligible to play (min. age limit to play is 17, 16 if doctor allows).
Vučkić said he was surprised to start, his first away game - on Anfield!
He was really bad in the first half, but he's improved in the second. He is not yet a player, who should start EPL games. Loan to Championship would be great for him.
Against WBA he played as central midfielder, against LFC he played as attacking midfielder in Slovenia U21 he plays as a right winger. He's a star in U21, on the last game he crated one goal, assisted one, and (almost) scored one - His teammate Robert Berić mistakely blocked the shot on the goal line.
Vučkić vs WBA - He had shaky first 15 minutes, then improved.
Some stats:
Playing time: 176 minutes (2 sub in, 1 sub out)
2 key passes
82% passing average (59/72)
40% accurate crosses (2/5)
2 times dispossessed
6 interceptions
...
Not bad for a 19 year old in a top 5 league, right?
p.s. Madridista calling other Madridista a clown? Brilliant.
