AS Roma striker Romelu Lukaku admits he's keeping a close on the Saudi Pro League.

Lukaku scored in yesterday's friendly win against Al Shabab.

The on-loan Chelsea striker said: "In the next two years I see this league becoming one of the best in the world, if not the best. The clubs make a lot of efforts to bring the 'big' players here.

"As a result, the teams and the footballing qualities are improving significantly."

Asked whether they can expect to see Lukaku in Saudi again, the 30-year-old replied "absolutely."
