4) Mario Mandzukic (Atletico Madrid)
A similar player to Giroud, but arguably an upgrade, Mario Mandzukic could be on his way out of Atletico Madrid this summer and has been linked with both Arsenal and Liverpool. A more proven player than Giroud, the Croatian international has won major honours in his time at Bayern Munich, netting in the Champions League final win over Dortmund at Wembley.
