Former Manchester United forward Terry Gibson has told Sky Sports that Elche striker Jonathas is similar to Diego Costa amid speculation over his future.
Jonathas, 26, enjoyed an impressive season on loan at Elche, scoring 14 goals for the La Liga side - but he must now return to Italy, with parent club Pescara no doubt rubbing their hands together at the prospect of landing a big fee for the Brazilian striker after a superb campaign.
A nomadic striker who really hit form in Spain, Jonathas is now hot property ahead of the summer transfer window, with Sky Sports pundit Graham Hunter suggesting on Revista de la Liga last month that Celtic were keen on signing Jonathas this summer.
The Bhoys saw Leigh Griffiths become a prolific striker under Ronny Deila, but with John Guidetti set to return to Manchester City at the end of his season-long loan deal and questions over the future of Stefan Scepovic after a poor debut season, Celtic will almost certainly be in the market for a new striker.
Given that Jonathas is still something of an unknown in British football, Sky Sports' Spanish football pundit Terry Gibson spoke in-depth about Jonathas - even comparing him to Chelsea hitman Diego Costa because of his strength and physical nature as a centre forward.
"Jonathas has surprised everyone," said Gibson. "He's been a bit of a traveller in terms of going around from club to club around Europe mostly, spending a season in Holland, the rest of his career has been Italy - this is the first season where he's really had an impact at a club."
"He's been really good. He got 14 league goals out of 35 that Elche scored, so it just goes to show how important he was. He fits the bill for a Premier League centre forward; if you're looking for a similar type of striker to Diego Costa, Jonathas could be your man," he added.
Celtic will be hoping that Premier League clubs choose not to target Jonathas this summer as they bid to lure him to Glasgow - but his goalscoring exploits in La Liga surely didn't go unnoticed, especially if he's seen as a poor man's Diego Costa.
