Manchester United are expected to tie up the move for Villarreal's Marcos Senna in the next few days.
Old Trafford boss Sir Alex Ferguson confirmed his interest in the Spanish international last week and is keen to push through a deal.
Both clubs have been locked in talks for the last weeks to try and thrash out a transfer.
Villarreal have now reluctantly decided to let the Brazil-born star leave for a fee in the region of é¼6 million (£4 million).
United are thought to have offered Senna a lucrative three-year deal to move from Spain to England.
Should Senna complete his move later this week he will become the second summer arrival at Old Trafford following the capture of Michael Carrick.
Meanwhile, Italian midfielder Alessio Tacchinardi is a major doubt for the opening game of the season against Real Madrid.
The former Juventus man picked up a leg injury in training last week and he faces up to three weeks on the sidelines.
Tacchinardi has bemoaned his luck so far this summer having also been sent off in the Intertoto Cup last month.
"This summer has not been the best," said Tacchinardi.
" My sending off in Slovenia (in the Intertoto Cup) the elimination in Europe and now this injury."
