City certainly have a penchant for poaching players from Arsenal. Toure, Emmanuel Adebayor, Gael Clichy and Samir Nasri have all swapped the Emirates for the Etihad in recent years, though the Gunners were of course well compensated, to the tune of more than £70 million.
Toure, however, has seen his career stall following his failure of a drug test. While he was merely guilty of taking his wife's slimming tablets, he was still handed a lengthy ban, which he has only recently finished serving.
Now the club is seeking to punish him further by denying him the windfall from his image rights, some £1.5 million. The row could result in Toure, who has seen City rise to the top of the Premier League table with Vincent Kompany and Joleon Lescott anchoring the defence, seeking to leave the club.
If that were to happen, then a cut-price return to Arsenal would not be the worst move for either party.
Toure could return to a club he knows inside and out from his seven years there, which included a key role in the 'Invincibles' side of 2003/04.
Wenger would regain the use of a player he knows would provide competition for places at the back, with Per Mertesacker still not impressing since his summer move, and the Ivorian could also play in midfield when necessary, the position he played in at the beginning of his Arsenal career.
