Chelsea are working hard to get a deal done for Enzo Fernandez today and now a new update has emerged from a reliable source on the situation unfolding in the final hours.

What's the latest?

CBS reporter Ben Jacobs has given an insight into Chelsea's attempt to complete a deal to sign the Benfica midfielder today.

Jacobs claimed in a Twitter space with Football Transfers this afternoon:

"It's all on Rui Costa, Benfica are in the Champions League and they don't want to sell, you would expect Rui Costa would delay into the afternoon whilst Benfica look at their own options for a replacement and they have a match today, Enzo Fernandez won't be involved.

"We're heading into an afternoon now where Rui Costa and quite a divided Benfica board will finally make a decision, this is what gives Chelsea still some hope and until we know the resolution of that meeting - I was told was after lunch - the picture will not be clearer which is why there hasn't been any significant progress this morning.

"Chelsea are ready to go they've agreed on terms with the player, they've got the logistics in place to complete the deal, so if it does happen late they will be able to pull it off, but it really is about getting that green light from Rui Costa which hasn't yet arrived."

Could be a Deadline Day howler

There is no doubt that Fernandez would be the cherry on top of an outstanding transfer window for the Blues, however, if the meeting held this afternoon does not end positively in Chelsea's favour it could be an absolute howler.

The west London club have already accepted a bid for Jorginho to join Arsenal before the transfer window closes in a few hours, which could mean that if Chelsea do not pull off this deal for Fernandez it could leave Graham Potter with extremely limited options in the centre of the pitch over the remainder of the season.

N'Golo Kante and Denis Zakaria are two midfielders that make up a long injury list at Stamford Bridge at the moment, so the exit of their experienced Italian titan could only add to a poor Deadline Day for Todd Boehly and co.

Fernandez has been a speculated transfer target for several Premier League clubs in January with Liverpool and Manchester United also credited with interest after the 22-year-old ace won the World Cup with Argentina last month.

However, it appears now Chelsea are in pole position to secure the youngster's signature as long as the Benfica president sanctions the move in the dying hours of the window.

With that being said, it will be interesting to see what the outcome of that final decision will be and whether Chelsea will look at other options available to them. Indeed, they must ensure someone else is lined up otherwise they will facing a late howler.
