The Blues are keen on signing Inter Milan striker Romelu Lukaku this summer after their boss Thomas Tuchel made the former Manchester United striker a key transfer target.
Chelsea have already had two bids rejected by Inter Milan for Lukaku but the Blues remain confident of signing the Belgian striker.
If Chelsea reach an agreement with Inter Milan for the transfer of Lukaku, the Red Devils are set to benefit from the transfer.
According to Daily Mail, Manchester United will be in line for a windfall of around £4m should Chelsea strike a £100m deal for Romelu Lukaku.
United had a sell on clause inserted in Lukaku’s contract when he left for Inter Milan that entitles them to around 4 per cent of any future sale fee.
