Frank Leboeuf ordered Graham Potter to drop Marc Cucurella as he declared the defender "doesn't belong" in a Chelsea shirt.
Cucurella, 24, has struggled to adapt to life at Stamford Bridge after joining the Blues from Brighton in a transfer worth over £60million last August. The left-back has made 24 appearances in all competitions this season, playing a prominent role partly due to Ben Chilwell's injury woes.
Although Chelsea have shown signs of improvement at the back in recent fixtures, Cucurella has hardly lived up to his lofty price tag, failing to register a goal or assist since late August. The Spaniard's form has not picked up since former Seagulls boss Potter replaced Thomas Tuchel in September, leaving Leboeuf in no doubt that he is "not good enough for Chelsea".
