#3 Sead Kolasinac
The one that almost got away. Both Manchester City and Liverpool wanted to sign Schalke defender Sead Kolasinac on a free transfer. Luckily for Arsenal fans, the Bosnia and Herzegovina international chose the Emirates.
Should Arsene Wenger play 3-4-3 just as he did towards the end of last season, then Kolasinac is certainly a good addition to the Premier League outfit.
Able to play on the left, the 24-year-old likes to get forward at every opportunity, whilst he has a lethal left-foot on him. Not only that, Kolasinac is able to play on the left side of a back three, something that Wenger will certainly have taken into account when signing him.
During his 24 Bundesliga games for Schalke last season, the Bosnian scored three and created five whilst averaging 7.32 (via Whoscored). Not only has he played at the highest level, Kolasinac as Champions League experience.
