After confirming the signing of Chelsea prospect Charly Musonda on Monday evening, transfer activity is again heating up at Celtic after a pretty quiet January all things considered.

The signing of defender Marvin Compper is the only other first team signing to arrive at Celtic Park this month, alongside St Mirren winger Lewis Morgan, who was loaned back to the Scottish Championship high flyers for the rest of the season.

After failing to make an impact in the UEFA Champions League and an important half-season ahead, fans were hoping for something of a refreshment of Brendan Rodgers' squad but barring deadline day drama could have to remain content with the business that's been done.

There's still time though and with injuries in key positions, potential mega money bids for established stars and all the usual craziness that comes at the end of January window, Celtic could still do some serious business.

These are the THREE deals that could still happen before the deadline...

In: Adam Bogdan (or any 'keeper really)

Signing a goalkeeper has been high on the list of priorities for Celtic supporters for a while now, but after a serious knee injury ruled out Craig Gordon for the next three months it's not a must before the window shuts.

Brendan Rodgers himself confirmed they were on the hunt for a goalkeeper and the Bhoys were reported to have had a bid for Motherwell man Trevor Carson rejected this week.

Celtic Quick News threw a new, interesting name into the equation on Tuesday, reporting that sources confirmed to them that the club were on the hunt for Liverpool man Adam Bogdan, also claiming that Joe Hart was on Celtic's radar.

Bogdan would certainly tick a few boxes for the Hoops. He has extensive club experience at Bolton Wanderers, 20 international caps for Hungary and at 30 years of age is potentially coming into his prime as a goalkeeper.

The 6ft 5in shot-stopper is on the hunt for regular football after returning from a lengthy lay-off due to injury and Celtic could be the perfect environment. It's certainly one to watch in the final hours of the window.

Out: Moussa Dembele

It appears that Moussa Dembele will be eternally linked with an exit away from Celtic until the day actually comes, but as we head into deadline day, could that day have finally arrived?

The Frenchman has made just a handful of starts for the club over the last couple of months and with just eight goals this term has struggled to replicate the impact he made in his debut season.

As reported by The Herald, the club rejected a fresh bid for the striker last week, with Brendan Rodgers expecting he won't be making a move away from Glasgow in the final days of the window.

However that follows intense speculation he could be making an exit, with assistant manager Chris Davies admitting his head may have been turned.

The final day of the January window can often be a sellers' market and with cash-rich clubs desperate to improve their squads for the second half of 2017/18, there may not be a better time for Celtic to sell.

In: John McGinn

It's time that Celtic start to plan for the future of their central midfield. Stuart Armstrong has just 18 months left on his contract at Celtic and has failed to commit his long-term future the club and at 32 years of age, Scott Brown is now spring chicken.

There are few better Scottish prospects around right now than Hibernian man John McGinn and it appears we are drawing closer to the player finally making an exit from Easter Road.

Hibs admitted right at the start of the transfer window, amidst interest from Celtic and West Ham, that they are open to offers for the Scotland international after a fine run of form that has helped Neil Lennon's side compete in the top six of the Scottish Premiership.

A boyhood Celtic supporter and with significant potential, it would be a shame if he left for English football and if the Hoops have the resources, perhaps this is the time to commit and spend what it takes to bring him to Glasgow.
