Romelu Lukaku is understood to disagree with manager Thomas Tuchel's assessment that he was in need of a rest in Chelsea's 2-0 victory over Lille on Tuesday.
Tuchel twice claimed that Lukaku had looked 'exhausted' in recent weeks, particularly in his infamous seven-touch performance against Crystal Palace, and dropped him for Tuesday's game in favour of Kai Havertz.
Havertz enjoyed an impressive showing in Lukaku's place and will be confident of starting Sunday's Carabao Cup final against Liverpool in the central striker role.
However, according to The Telegraph, the Belgian has not given up hope of starting that game and intends to try and prove to Tuchel that he was wrong to blame his poor recent form on fatigue.
It is understood that Lukaku believed he was fit to start against Lille and was keen to get the nod, although he showed no signs of discontent and was happy to see Havertz performing well.
Lukaku still thinks he is in top physical condition and intends to keep it that way heading into Sunday's final, where he hopes Tuchel will give him his first taste of a Wembley final as a Chelsea player.
Interestingly, Lukaku was the only unused substitute not to join in with the usual post-match warm down, and Tuchel confessed that he was not actually sure why the Belgian was not involved but stressed that there will have been a genuine reason.
"I don't actually know, the fitness guys take care of that," the boss explained. "They for sure have a reason if he was not out. They have individual programmes for each player."
