Arsenal striker Joel Campbell ready for Real Betis loan

Arsenal striker Joel Campbell has spoken of his excitement ahead of a season-long loan move to Spanish side Real Betis.

The Costa Rica international will continue his development in La Liga after spending last season on loan with French team Lorient.

"It's a great opportunity for me to grow," Campbell told Fox TV. "I am going to the world's best league, and I want to play."

The 20-year-old striker signed for Arsenal last summer from Deportivo Saprissa but has so far failed to obtain a work permit to play in England.

Capped 14 times by his country and the owner of a memorable goal against world champions Spain, Campbell is seen as a raw talent with huge potential.

Arsenal manager Arsene Wenger is expected to be keeping an eye on Campbell's development over the next year.
