Real Betis striker Joel Campbell has thanked Arsenal's medics for helping in his recovery.

The Costa Rica international joined Betis on-loan in August carrying an injury.

Campbell is now available for selection and declared: "I tried to get to my best physically possible these days, I wanted to recover well and that's why I was not with my team (Costa Rica).

"I'm giving one hundred percent in training, that's what I have to do to be good and able to contribute my bit for the team.

"It was a great job on the part of the medical team and the Arsenal people who supported me at the time, thanks also to the people of the Costa Rican team, my sister and all those people who were behind me."
