Arsenal will challenge Tottenham for Real Betis winger Alvaro Vadillo.

The Mirror says Vadillo, 18, is seen as one of Spain's best prospects and has been compared to a young Cristiano Ronaldo.

Now, the two north London heavyweights, who meet on Sunday, the day before the summer transfer window closes, are chasing him.

Spain Under-20 starlet Vadillo has a £17million buy-out clause in his contract.

But Arsenal boss Wenger, who has detailed his scouts to watch the player, would hope to get him for less than that fee.
