Maurizio Sarri has dismissed the chances of Ruben Loftus-Cheek leaving Chelsea on loan in January.
Loftus-Cheek fired a fine hat-trick in the 3-1 Europa League win over BATE Borisov last month, but is yet to start a Premier League game under new boss Sarri.
The 22-year-old featured off the bench in the 4-0 league win at Burnley, but has been linked with a move away from Stamford Bridge.
Crystal Palace are interested after failing to bring Loftus-Cheek back to Selhurst Park in the summer, and are unlikely to succeed if they try again in the winter.
“Ruben in October played four matches out of five, so I think that at the moment the situation is not for loan, of course,” said Sarri.
“He has improved, but I think he still needs to improve more from a tactical point of view.
“The rest is good. He has great physical characteristics, he’s fast, solid, he has impact, and technically he is very good. I think that if he wants to play like a midfielder he has to improve in the defensive phase at the moment, but his potential is great.”
