Celtic are continuing to work on a deal to make Jota the biggest signing of the Ange Postecoglou era, according to journalist Pete O’Rourke, talking to Give Me Sport.

The Lowdown: January rumours

The Hoops have been busy this month, bringing in five players so far with days remaining of the January window.

However, they are yet to make Jota or Cameron Carter-Vickers’ moves permanent, despite opening talks with Benfica and Tottenham at the beginning of the month.

Celtic have an option to sign Jota permanently in the region of £6.5m, with the 22-year-old recently returning to action following a hamstring injury.

The Latest: O’Rourke’s comments

O’Rourke was talking to Give Me Sport regarding a permanent swoop for Jota. He believes the Hoops hierarchy are working on a deal and may not be announced until the end of the season.

“I think this one's something that Celtic are continuing to work on and will work on it during the end of the season and hopefully get it done ahead of next season in the summer transfer window.”

The Verdict: End the month on a high?

It’s clear that Celtic want to activate their option in the season-long loan agreement early, and if they can, £6.5m would be the most expensive signing of the Postecoglou era, surpassing a £4.86m move for Kyogo Furuhashi.

Finalising a move before the summer will also give Michael Nicholson one less thing to worry about heading into the next campaign.

A permanent January transfer could also help Jota in regards to the winger having clarity on his long-term future, and who knows, Postecoglou could reap the rewards of that on the pitch before the end of the season.
