Joel Campbell unsure of Arsenal future

The Costa Rican attacker Joel Campbell is unsure of his Arsenal future as he returns to the club for pre-season training. The 26-year-old did not take part in Arsenal's pre-season trip to Singapore, and instead will report to London this weekend to join up with the club. "This weekend, I'm traveling and they'll decide what's coming next," Campbell told La Nacion. "I know that I have a lot left to show in football, so where I'll do things as well as possible to enjoy this sport."
