Former Arsenal star Alexander Hleb has been remarkably open in recent years about how much he regrets his decision to leave the Gunners and join Barcelona in 2008.
The former Belarus international divided opinion for much of his time at Arsenal, having started slowly before really starting to show glimpses of his best form in his final season at the Emirates Stadium.
That prompted Barca to move for Hleb, and things went downhill from there, with the silky playmaker not getting much playing time in that famous Pep Guardiola side.
