Real Betis coach Pepe Mel admits bigger clubs are following winger Alvaro Vadillo.

The teenager is a target for Manchester United and Real Madrid.

Vadillo is set to be out of action for six months after damaging his knee ligaments against Real Madrid last weekend, but coach Pepe Mel had some news to cheer him up.

"I advised him that he could use the months that he is out to learn English," Mel told Marca.

"We are studying offers for him and there has been a concrete one recently from a foreign team.

"But if he is worth 4million euros today after playing 30 matches then, for example, he could be worth 12million euros and so on."
