4) Arsenal
Poor Arsene Wenger. It has been seven seasons since he saw Arsenal drawn in the quarter-final draw of the Champions League. Twice in that streak, it was Lionel Messi who wreaked havoc and knocked them out. Of course, he has also met them before in the quarter-final. In all, he has scored nine goals against Arsenal – a record in the Champions League.
So if Wenger wants to go out on a high following 20 years of both success and failure, why not sign his greatest nemesis? It would immediately elevate Arsenal to worthy title contenders and allow them to at least look up in awe when they reach the latter stages of the knockout rounds of the Champions League.
It would be the statement of intent that has long been missing ever since he built the Invincibles squad back in the early 2000s. Mesut Ozil and Alexis Sanchez would hurriedly sign their contract extensions and Messi would automatically replace the erratic Theo Walcott in the starting lineup.
Even if Wenger were to leave and Max Allegri came in to do justice to all those rumours going about, the Italian is known to be a master tactician and would easily find a place for Messi on the pitch.
