Shakhtar Donetsk coach Mircea Lucescu says they must not sell Alex Teixeira on the cheap.

Liverpool had a revised £28million bid for the free-scoring Brazilian rejected earlier this week with the Ukraine club holding out for closer to their €50m valuation.

"He's worth €50m," Lucescu told FourFourTwo.

"He's incredible, very fast, very good technique. I compare him with other players of the same age who changed [the fortunes of] a club, Di Maria for example at Paris Saint Germain.

"Teixeira can be at the same level, better even. He doesn't get injured, and every year he gets better and better."
