Champions League winner Owen Hargreaves was full of praise for Thomas Partey after Arsenal's Europa League defeat of Rapid Vienna.
Partey, who came on as a late substitute in the Premier League at the weekend, shone in his full debut for Arsenal as they came from behind to win 2-1.
"Thomas Partey had one of the best debuts I've ever seen, honestly," Hargreaves declared on BT Sport.
"He's ran the whole game and you can tell he's been playing in the Champions League because it looks too easy for him.
“We saw before the whole range. Short, long, playing between the lines. Physically, that's what he's in there for, a little bit of steel.
“With the centre-backs, boys get in bad positions, don't worry, I'm there."
