TiemoueBakayoko is looking for an escape route from Chelsea on loan once again but the Blues are dissatisfied with the offers put forward by Monaco, report Goal.
The 25-year-old's entourage was in the principality on Tuesday to try to find a breakthrough but Chelsea director Marina Granovskaia will not accept the current proposals.
The Blues signed Bakayoko for £40 million ($49m) in 2017 from Monaco and are hoping to make most of their money back in any sale of the player.
AC Milan had the option to buy Bakayoko for €35m (£32m/$39m) in their loan arrangement last season but decided against it after failing to qualify for the Champions League. Monaco, who are also thought to be interested in Southampton midfielder Mario Lemina, are not keen on including a big redemption clause after Paris Saint-Germain were the latest club to decide against signing the once-capped France international.
Blues manager Frank Lampard has spoken about the futures of both Bakayoko and Zappacosta, the latter of whom has arrived in Rome and is having his medical on Wednesday.
"Yes, it is similar with both players," Lampard said of Bakayoko and Zappacosta in a press conference last week.
"They obviously haven’t both started this season for us or had minutes. Both have shown great application and not been a problem. The decision will be what’s best for us as a club and them individually."
