Anglo-Nigerian striker Dominic Solanke wants £50,000 a week and the promise of first-team opportunities if he is to sign a new contract at Chelsea.
Solanke, who has played a total of 17 minutes in a Chelsea shirt, has one year left on his £8,000 a week deal and contract talks have stalled, as revealed by Sportsmail last week.
The Blues rate the England Under-21 international highly and are committed to their youth system but are determined not to be held to ransom.
Solanke has made one first-team appearance for the club and has spent this year on loan in Holland.
It will be a bitter blow if Chelsea are to lose the youngster, long since identified as one of the academy products capable of bridging the void into the first team.
Jose Mourinho once offered to shoulder the blame if he did not go on to play for England at senior level.
Solanke joined the club in the Under 8s but he and his family have grown concerned by the lack of opportunities for young players at Stamford Bridge.
He made his first-team debut last season in the Champions League against Maribor but has spent this campaign on loan at Vitesse Arnhem, where he has scored seven goals in 24 appearances.
Chelsea’s struggles to keep hold of the forward are part of a worrying trend and one which technical director Michael Emenalo is determined to address.
Emenalo’s academy has consistently produced exciting players at 17 and 18 in recent years – and won many trophies – but establishing a pathway into the first team has proved difficult.
The reasons are varied but the impact has become tangible with growing discontent in the development ranks, where young players see Hector Bellerin given the chance at Arsenal, Jordan Ibe at Liverpool and Dele Alli at Tottenham.
