#3 Denis Suarez (Barcelona to Arsenal - Loan)
Arsenal saw their long-standing interest in the Barcelona player materialise in the January window this year with a loan deal and an option to buy in the summer. The 25-year old attacking midfielder has already played for the manager Unai Emery at Sevilla, where the player was largely successful and influential in winning the Europa League title.
Suarez has the pedigree for top-level football having played for big clubs during his young career and is currently settling in the league having made five appearances for the Gunners already. Interestingly, Suarez already has a history in England and has been a part of Manchester City set-up from 2011-13. As Arsenal push for a place in the top-four, Denis is expected to add the much-needed depth and flair in the midfield since he can play either on the flanks or through the middle.
He has been involved five times for Arsenal this season however, he hasn't established himself completely with the squad yet. All the five appearances he has made for the club since his move has been off the bench coming on as a substitute.
