Chelsea star Fikayo Tomori has admitted he has had to battle with his team-mates to prove he is worth a starting spot. Frank Lampard has only been in charge of the Blues since the summer.
And the ex-Derby boss has struggled to come across a winning combination in defence. Chelsea have been used to strong foundations but this campaign has exposed some frailties, though this can be pinned on their youth.
Antonio Rudiger is the most experienced defender in their ranks and he has only just recently turned 27. The German has been Lampard's go-to man at the back, while Kurt Zouma, Fikayo Tomori and Andreas Christensen have all vied with one another as well.
