Carlos Vela's future looks far from clear, and far from straight-forward. The Real Sociedad man has enjoyed two strong seasons in Spain following his departure from Arsenal back in 2011, scoring 30 goals in 72 league matches.
It seems as though that form has caught the eye of Arsenal boss Arsene Wenger who would like to take him back to north London - and will use the £3.5 million buy-back clause written into the Mexican's contract to do just that.
However the story doesn't end there - according to reports Arsenal don't believe that Vela can be a success in the Premier League, and will actually sell him on immediately at a much higher price.
That's where the story takes a new twist. According to Spanish source El Confidencial, Atletico Madrid have included Vela on their list of possible replacements for Chelsea bound Diego Costa.
They say that Vela is being lined up alongside the likes of Alvaro Negredo and Chelsea youngster Romelu Lukaku to step into the shoes of Costa, who is close to moving to Stamford Bridge in a deal worth £32 million.
That could work perfectly for Arsenal and Vela, who appears happy in Spain and would reportedly like to stay there. The Gunners could command a hefty fee from a team who have just pocketed £32 million from Chelsea, while the striker would be joining the reigning La Liga champions.
However an issue that could further complicate Vela's future is Arsenal's apparent interest in Joseba Zaldúa. According to El Confidencial, the Gunners could make a bid for the right-back shortly as part of a double deal for the striker.
It is unclear what that could mean in terms of how much Arsenal would pay for Vela - they may be willing to offer more that his release fee if it persuades Real Sociedad to do business over Zaldúa.
Should Atletico not be able to work out a deal for Vela, then Negredo may represent a more likely move; the Spaniard started his first season with Manchester City on fire but faded badly and didn't find the back of the net from January 12 onwards in the Premier League.
Lukaku is also an option, but Chelsea won't include him on their deal with Costa, which means Madrid will likely have to cough up around £25 million.
