Real Sociedad have secured the services of Carlos Vela until 2018 after Arsenal opted not to take up their option to re-sign the Mexico striker, with the Gunners set to receive up to €15million from the deal.

The 25-year-old Mexico international initially joined Sociedad on loan from Arsenal in 2011 before making the switch permanent in 2012, with the Gunners retaining the option to buy the player back.

Arsenal have now decided against bringing Vela back to London and have agreed a deal with the Spanish club understood to be worth up to €15million for Vela to become Sociedad’s player exclusively.

A statement on www.realsociedad.com read: “Real Sociedad have reached an agreement with Arsenal for Carlos Vela to continue at the txuri urdin club.

“Real Sociedad have also reached an agreement with Carlos Vela to renew his contract for the next four seasons. The previous agreement finished in 2016. The Mexican striker has already signed his new contract.”

Vela has scored 47 goals in 126 matches for Sociedad, helping them finish fourth in La Liga in 2013 and seventh last term.
