Tammy Abraham 'has asked Chelsea for a new contract worth £130,000-a-week' to match that of his fellow academy graduate Callum Hudson-Odoi.
The England forward, 22, who has scored 15 goals during a breakthrough season at Stamford Bridge, has two years remaining on his current £50,000-a-week deal.
According to The Times, Abraham has been waiting for Chelsea's moves in the summer transfer market before deciding his future.
But if he is to remain at the club, Abraham has reportedly been using Hudson-Odoi's £120,000-a-week plus bonuses contract as a yardstick for his own salary.
New signing Timo Werner, the Germany international striker, agreed a five-year contract worth £170,000-a-week ahead of next season.
Academy graduate Abraham enjoyed a fine start to the season but suffered a couple of minor injury setbacks before football shut down in March and the goals have dried up.
His last Chelsea goal came against Burnley on January 11 and Abraham was dropped by manager Frank Lampard for Saturday's 3-0 win over Watford.
Lampard isn't yet concerned about Abraham's contract situation, saying: 'Tammy's contract is not at a critical level and I will leave it to him and the club to discuss.
