Chelsea's interest in teenage Brazilian wonderkid Estevao Willian may not be so straightforward.

The Stamford Bridge club were hoping to wrap up a deal for the youngster, who is still not 18.

However, Mundo Deportivo in Spain state that Arsenal are also eager to sign the 16-year-old.

Chelsea are said to have put in a bid, but Arsenal are ready to go even higher.

Despite his supreme talent, Premier League clubs would be taking a chance on Estevao.

The forward is not eligible to play in England until he turns 18, which means he would have to be loaned out until that time.
