The defender, who arrived on a free transfer has already impressed for the Gunners and looks to be well on his way to becoming a cult hero.
Arsenal head to the Britannia Stadium for a game which is bound to have an edge, but Wenger says Kolasinac brings great strength to the Arsenal side.
“Maybe he [Kolasinac] is the strongest [I have worked with],” he said via the Mirror.
“He is naturally strong. He uses quite well the strength of his body without violence and when he intervenes it doesn’t look to be a foul, he just uses his body strength. It is an important quality to help adapt to the Premier League.
“He has the capacity to repeat runs, and we noticed when we watched him play that he is quite dangerous in the final third.”

Wenger also admitted it had been an easy decision to decide to bring him to Arsenal, after watching him in action for Schalke.
“Watching him, I thought he had the quality. I met him and he had a good spirit and a good attitude so basically it was a no-brainer for us,” he added.
“It is a nice bargain yes and you might find it more and more.
“I have said it many times, that more and more players will go to the end of their contract because the transfer fee is too high, the inflation is too high and the agents will be demanding and clubs will not be in a position to extend contracts.”
Kolasinac has looked an absolutely superb signing so far and it will be interesting to see how he fares on Saturday, should he start the game.
