Uruguay international Forlan regained his scoring touch in Spain after struggling to make an impact in the Premier League.

And boss Juande Ramos is looking to add to his forward line since the departure of Robbie Keane and expected move of Dimitar Berbatov.

Spurs were also close to securing the £7m capture of Corluka.

Meanwhile, United's Wayne Rooney is unlikely to be fit for the start of the season after contracting a virus on the club's pre-season trip to Nigeria.

United played four friendlies, including one against Community Shield opponents Portsmouth, on the tour but it now looks to have cost them the services of their leading striker.

Manager Sir Alex Ferguson told Sky Sports News: "I doubt we'll get Rooney fit for the start of the season with the virus he's had.

"It's a virus he picked up in Nigeria and it's not a nice one, but quite a few have had it.

"It's such a bad virus and he's got to be training to be fit."

Ferguson confirmed that Rooney was not suffering from malaria, against which the entire squad had been treated before the trip.
