Atletico Madrid striker Diego Forlan has confirmed former Manchester United teammate Roy Keane wanted to sign him for Sunderland.
"Roy Keane's charisma, his personality on and off the pitch - he's a gentleman," said Forlan.
"In training he'd explain things in a good way - and sometimes in a bad way, because it mattered.
"When he was boss at Sunderland, he called me all the time to go and play for him."
