Chelsea have agreed a new long-term contract with Ruben Loftus-Cheek that will provide head coach Frank Lampard with an immediate boost to his reign.

Lampard’s return is due to be officially announced by Chelsea on Wednesday and should roughly coincide with Loftus-Cheek committing his future to the Blues.

Chelsea are yet to confirm the details of Loftus-Cheek’s new contract, but it is expected to run for at least five years and could be worth over £150,000-a-week.

That would represent a stunning rise, as Loftus-Cheek’s last deal, which he signed three years ago, earned him £60,000-a-week.

That contract had two years left to run, but Chelsea were determined to secure Loftus-Cheek to a new agreement even though he is recovering from a serious injury.

Loftus Cheek may not play again this year after rupturing his Achilles tendon and missing the Europa League final, but he had already proved himself over the final months of last season.

Having secured a place in former head coach Maurizio Sarri’s team, Loftus-Cheek finished his breakthrough season with 10 goals which was only beaten by Eden Hazard, Olivier Giroud and Pedro.
