Chelsea are set to miss out on signing Zenit St. Petersburg midfielder Leandro Paredes, with Paris Saint-Germain willing to meet the Russian club's asking price.
Goal understands the Ligue 1 leaders have made an offer of €40 million (£34.9m/$45.5m) for the Argentina international, with a further €5m (£4.1m/$5.7m) to be paid in commissions.
Chelsea value the player are closer to €30m (£27m/$34m), and as such will be forced to look elsewhere in their search for midfield reinrforcements with Zenit chief Alexey Miller likely to accept PSG's offer.
The Blues had hoped to bring the 24-year-old to Stamford Bridge as they try to replace the hole left in their squad following Cesc Fabregas' departure to Monaco.
Maurizio Sarri is keen to bring in a midfielder with a strong technical ability to act as a deputy to first choice Jorginho.
That player is unlikely to be Paredes, however, with PSG's hunt for a defensive midfielder of their own during the January transfer window set to come to an end.
They have been linked with Everton's Idrissa Gueye, Watford's Abdoulaye Doucoure and Borussia Dortmund's Julian Weigl during the course of the winter window as Thomas Tuchel looks to add to his own roster.

"It's January 21 and we have needs," Tuchel told reporters ahead of his side's Coupe de France victory over Strasbourg on Wednesday.
"We lost Adrien Rabiot, Lass Diarra and Marco Verratti, the situation has not improved.
"We stay with our decision [on Rabiot] because Marco returns in a few weeks. We stay with our basic choice.
"We have recovered Dani Alves in this role but it is very, very serious for us. Who do I want? Yeah, yeah, I know. Unfortunately I cannot tell you!"
PSG had previously held an interest in Chelsea's own N'Golo Kante, but following his decision to sign a new five-year deal with the Blues in November the French champions have decided taking that any further.
