Chelsea will not grant Derby County with permission for their loanees to feature against their parent club, ESPN reports.
The Rams, under the guidance of Blues legend Frank Lampard, saw off Manchester United in the third round to set-up a mouthwatering clash at Stamford Bridge – but the Championship side will be without two key players.
Derby were hoping that Chelsea would grant them permission for Mason Mount and Fikayo Tomori, who are on loan from the Blues, to feature in the fourth-round tie but will not be given the ‘written consent’ they require.
All Chelsea’s domestic loanees have it written in their contracts that they cannot play against the Blues and the West London outfit see no reason for their stance to change, having also not given Hull City permission in an FA Cup tie last season.
Mount will be the biggest loss for Derby after his starring performances so far this season, scoring three goals and registering an assist in ten appearances to help his side sit ninth in the Championship standings.
