Mexican forward Vela arrived at in North London from Guadalajara back in 2005, and after loan spells in Spain with Salamanca and Osasuna, Vela was promoted to the Arsenal first team - only to make just 29 league appearances, scoring three goals.
A loan spell with West Bromwich Albion also failed to bear any fruit, and was farmed out to another Spanish side in Real Sociedad. The move was eventually made permanent, and Vela - now 25 - has a stunning record for the San Sebastian side, making 111 appearances, scoring 41 goals and laying on 27 assists too.
Well, you can now make it 42 goals after Vela gave Jagoba Arrasate's side the lead over Real Valladolid, notching a goal reminiscent of his Arsenal days. When he did score goals - mostly in cup competitions - Vela was known for scoring delicate lobs, and his strike tonight was no different.
With Olivier Giroud lacking real support in the Arsenal attack, Vela had been linked with a return to the Emirates Stadium, and with the Gunners' title challenge falling away late into the season, manager Arsene Wenger could certainly do with the kind of spark that Vela provided Sociedad tonight.
