It's no secret that success isn't always guaranteed after that multi-million pound move to one of Europe's top clubs.
Career-threatening injuries, the inability to perform at an optimal level and henceforth failing to make the cut, coupled with ongoing interest from abroad, are just a few of several factors that could effectively play a key role in troubling a player during his career as a top-flight footballer at a certain club.
And Arsenal Football Club is no different: from players having their heads turned by challenges fresh and pastures new, to signing on young talent that eventually either fail to make the grade or simply end up getting their legs crocked from a tackle, the Gunners have also seen their fair share of troubled superstars over the years.
So without further explanation, here is a ranked list comprising 5 players that flopped - or are still performing at a subpar level—with the Gunners.
P.S: I'm well aware other players may have just as easily made this list. Feel free to post suggestions in the comments below.
