Donyell Malen
His asking price has been reported as being between £35m and £50m but the impact of the global health crisis may lead to his club PSV asking for a lot less in order to balance the books.
Malen also underwent minor knee surgery in January which may also stop Liverpool from making a bid, but the former Arsenal striker scored 17 goals in 25 games last season. He is also capable of playing right across the front three.
