Manchester United have been told to up their bid for River Plate sensation Ezequiel Cirigliano.

United are understood to have tabled a £5 million offer for the 20 year-old midfielder, but River won't let him leave for such a sum.

Ole says United have been informed to pay Cirigliano's buyout clause - £12.5 million - if they want to sign the youngster.

River need to sell to balance the books, but won't be taken for mugs by the Premier League giants.
