The Liverpool defender looks set to join Norwich City.
The youngster looks destined to leave the club this summer after failing to agree a new deal.
The Canaries have already made a bid for his services, with the Liverpool Echo reporting earlier this week that they have seen a £2.5 million bid accepted by the Reds.
He has been negotiating with the Championship club since then over a proposed move to the club.
The £2.5 million fee was seen as something of a coup for Jurgen Klopp’s side, but it now transpires they may make a bigger profit on their youngster.
According to the Liverpool Echo, they could now make up to £4.5 million for the Spanish midfielder.
They report that an initial £2.5 million deal has been agreed but that there is a further £2.5 million in performance related add-ons in the deal.
They have also negotiated buy back and sell-on clauses for Canos, meaning the deal could prove to be a very lucrative one for them should he flourish at Norwich.
