Carvalho has emerged as Liverpool’s top target on deadline day and the club are in talks with Fulham for his signature.
The 19-year-old will be out of contract in the summer but Liverpool want to avoid going through a tribunal to agree on a fee for him at the end of the season.
They are also wary of losing the attacking midfielder out to a club outside England and are trying to negotiate a fee with Fulham today.
But the Championship club are driving a hard bargain to secure the best deal possible for the club.
Fulham are standing their ground in order to get, what they feel, is a fair fee for a talented young midfielder.
The Merseyside giants are keen to get a deal over the line but for the moment there is no agreement.
Liverpool are prepared to let Carvalho spend the rest of the season at Fulham even if they sign him.
