Paul Merson has claimed that Chelsea manager Graham Potter didn't sanction the signing of Mykhailo Mudryk.
Mudryk was one of a host of arrivals at Stamford Bridge in January as he signed from Shakhtar Donetsk for £88million.
However, despite an encouraging debut against Liverpool, the winger has yet to establish himself as a regular starter for Potter's side.
In Chelsea's 2-0 defeat to Tottenham, when they were sorely lacking in attacking inspiration, Mudryk only featured as a substitute, playing just seven minutes.
Merson stated that if Potter had overseen Mudryk's signing then he would have started him.
