Liverpool boss Rafa Benitez must make a major sale this month.

The Mail on Sunday says Benitez has been asked by the club's owners to find a buyer for Momo Sissoko to finance the £6m purchase of Slovakia defender Martin Skrtel.

American owners Tom Hicks and George Gillett sanctioned the purchase of centre-back Skrtel believing that Sissoko's £10m move to Juventus was imminent. However, that fell through.

Benitez is now under pressure to get the best price while Sissoko is on Africa Cup of Nations duty for Mali.
