Chelsea was drawn against Derby County which could have been deemed as an issue, however, Chelsea are happy to allow their players to play against them.
Unlike in the Premier League, EFL Cup rules allow for clubs in the competition to make such agreements for players to appear against their parent clubs.
“Chelsea Football Club has today granted Derby County permission to select loanees Mason Mount and Fikayo Tomori for next week’s Carabao Cup fourth-round fixture,” a statement issued on the Blues’ official website read.
“Unlike in the Premier League, EFL Cup rules allow for clubs in the competition to make such agreements for players to appear against their parent clubs.
“Mount and Tomori have been regulars for the Rams under Frank Lampard this season, and, after beating Manchester United at Old Trafford in the previous round, we believe the experience of facing top-level opposition once more will be of benefit to their on-going development at Derby.”
Mount and Tomori have impressed many whilst with Derby and were both hugely influential in the club’s victory away at Old Trafford against Manchester United.
England U20 defender Tomori has been part of a back-line which has kept five clean sheets already this campaign.
The tie will also see former Chelsea midfielder and club legend Frank Lampard return to Stamford Bridge.
Speaking to Derby’s official website, Lampard added: “I would like to take this opportunity to thank Chelsea, their director Marina Granovskaia and manager Maurizio Sarri for allowing Mason and Fikayo to be available for selection for the Carabao Cup tie.
“We’ve been in dialogue with Chelsea since the draw was made and it’s great, first and foremost, that the players will have the opportunity to test themselves against a top side.”
