Theo Walcott has labelled new Arsenal team-mate Sead Kolasinac an "absolute animal" who will be perfectly at home in the Premier League.
The defender scored his first Gunners goal on his competitive debut for the club as they beat London rivals Chelsea 4-1 on penalties - following a 1-1 draw - to lift the Community Shield.
Kolasinac headed home a late equaliser following Pedro's red card after Victor Moses had put the Blues ahead.
Signed on a free transfer from Schalke, the 24-year-old replaced captain Per Mertesacker, after he suffered a head injury, and impressed with his strength and aggression.
"Honestly, he is an absolute animal," he said of Kolasinac.
"He's incredible. I see him in the gym every day, you can just tell he looks after himself well, he eats the right food and he's professional."
