Manchester United are preparing a €32m (£27.3m) bid for Spain international Javi Martinez, according to reports in Spain.
The Athletic Bilbao midfielder - who had a €32m buy-out clause inserted into his latest contract - has attracted interest from across Europe after impressing for the Spanish national side.
Martinez has been linked with a move to Manchester United after a string of stand-out performances in the holding midfield role as well as in central defence.
However, the United-target distanced himself from speculation connecting him with a move away from Spain earlier this month.
"When you hear of interest from United, you feel proud but I'm happy at Athletic," the midfielder said earlier in November.
Meanwhile, Manchester United winger Ashley Young insists they will not play for a draw in Wednesday's crucial Champions League clash with FC Basle.
Sir Alex Ferguson's side require a draw in Switzerland to secure their place in the last-16 but, after relinquishing a two-goal lead in the corresponding fixture at Old Trafford, Young admits the side are taking nothing for granted.
"It would be dangerous to think we only need a draw," said the Manchester United star. "No-one at this club has that mentality.
"We still have it in our hands to go there and qualify, which was the main target and we will be trying to win."
