Since his move to Spain to Real Sociedad in 2011, Carlos Vela has begun to show the footballing world that the form he displayed as a youngster may well lead to a top class player.
In his four years in the Premier League with Arsenal and West Brom, the Mexican struggled to earn regular playing time, and wasn't quite capable of coming to terms with the pace and power of English football.
Though Arsene Wenger was reluctant to part with him, he agreed to let the forward move to La Liga after a disappointing loan spell at the Baggies in 2011 failed to reap much reward.
Vela has been a revelation since heading to Spain, improving year on year to register 47 goals and 29 assists in 123 games - a record better than a goal contribution every 2 matches.
Coupled with the fact Wenger was reported to have included a £3 million buyback clause as part of the switch to Real Sociedad, it's easy to see why the Frenchman is reconsidering a return swoop for Vela.
But aside from the price, there is little reason in bringing the player back to North London.
Many of Vela's strong performances for Real Sociedad have come from the right wing, a position the Gunners are very strong in with both Theo Walcott and Alex Oxlade-Chamberlain available. Arsenal also have Serge Gnabry beyond the two Englishmen, who at 19 this July, will surely be eager to earn more first team games next year.
He could switch to the other wing, but with Lukas Podolski hitting some form towards the end of the season, and Santi Cazorla also tending to occupy that position, Vela will again struggle to get game time.
Which means that he would have to be signed as a striker alternative to Olivier Giroud. Say what you want about the former Montpellier man, he is still the big, strong target man that Wenger has been seeking to utilise for much of the season. It seems that the Arsenal boss is so eager to go with a big man up front that he selected Yaya Sanogo ahead of more proven goalgetters Podolski and Walcott when Giroud was suffering from a lapse in form. Vela, who is a smaller, tricksier player much better playing off someone like Giroud, would possibly only succeed here if Wenger went with two up top, something he is unlikely to do.
All together this indicates the Mexican may struggle to win a regular place at the Emirates, much like he did in his last spell at the club.
Given the possible resale value a deal for Vela would have, it looks like the major benefit of a move for the player would be selling him on to another club for an improved profit.
