Ferran Torres is nearing a £55m switch to Barcelona from Man City in the January transfer window - but how are the cash-strapped Catalans (who have a £849MILLION debt) able to sign the forward and can he play straight away?

Manchester City may be firing on all cylinders but they're about to lose a part of their firepower in Ferran Torres.

Torres is set to join Barcelona in the January transfer window after the two clubs agreed a deal - despite the Spanish giants' crippling debt.

So how has the impending move come about - especially in light of Barca's messy finances? Sportsmail takes a look...

What has been agreed?

In principal, a transfer fee that should rise beyond £55million, making Torres the most expensive player sold in Manchester City's history - just eclipsing Leroy Sane's departure to Bayern Munich.
