Arsene Wenger believes he has won the race to sign Schalke left back Sead Kolasinac . The Gunners boss appears to have beaten off competition from AC Milan and Everton to sign the 23-year-old Bosnia and Herzegovina international. Kolasinac has been offered a four year contract, can play left wing back and is seen as the club’s long term first choice. Wenger played down the story at his press conference but Arsenal are confident the deal is done for the full back who is a free agent in the summer.
