With the January transfer now in full swing, Celtic have wrapped up three deals already. The Hoops do not look like they’re finished there though, so we’ve put together an update of some possible ins and outs that could still happen before deadline day at the end of the month.

Oliver Burke joined the Hoops on a six-month loan from West Brom to bolster Brendan Rodgers’ options in wide areas along with young sensation Timothy Weah joining on loan till the end of the season.

Celtic’s third deal of the month saw a permanent move for striker Vakoun Issouf Bayo for around £2 million from Slovakian side Dunajska Streda on a four-year contract.

With a new front three in the bag, it seems the focus will now turn to defensive matters for the team with a new right-back desperately needed to refresh the struggling Mikael Lustig and also a new centre-back to replace Dedryck Boyata who looks likely to leave when his contract expires in the summer.

Possible ins

Timothy Castagne – As reported at the start of the window, it seemed Celtic were keen to sign the Belgian international full-back who currently plies his trade in Serie A with Atalanta.

At the time it seemed a £6 million deal had the potential to bring the 23-year-old to Glasgow but now the longer this rumour drags on, the less likely it seems Celtic will win his signature.

With other suitors sniffing around, a deal could now rise to a reported£10 million, which may put him out of Celtic’s reach. Whilst a deal is not dead, it looks unlikely at this stage.

Omar Elabdellaoui – A more financially viable option at right back could come in the shape of the 27-year-old from Olympiacos, who would cost around £4 million. The Norwegian international who has 34 caps for his country still has two years left on his current deal in Greece but it seems Celtic have taken an interest.

Andrew Gutman – The American left back could be set to join Celtic this month despite having a trial at Rangers in December. In the modern world of the transfer market, Gutman has dropped a hint of a deal after following Celtic’s official Twitter page.

Despite not having made a professional start in the game as yet, the 22-year-old has won the Hermann Trophy for his impressive performances for the Indiana Hoosiers at college level.

Gutman is likely to be brought in as an understudy to Kieran Tierney, with Emilio Izaguirre out of contract this summer.

Manny Perez – Another American who could be on his way to Celtic after the right-back spent a week on trial at Lennoxtown in December.

The 19-year-old seems to have impressed Brendan Rodgers and could be a project signing for the future with a more experienced right-back likely to be on the club’s radar.

Scott McKenna – It is clear the Aberdeen defender is well liked by Celtic after they attempted to sign the Scot in the summer. Whilst this month, talks of a deal have been quieter, a move wouldn’t be a surprise given his clear potential and his strengths in the Scottish game.

Possible outs

Scott Brown – Over the festive period, it seemed a real possibility that Celtic’s captain could opt for a move down under with Western Melbourne.

However, the Aussie’s first contact offer has been knocked back as it looks as though they may be priced out of a deal.

Despite this, the 33-year-old’s current deal ends in the summer so January will be an interesting month as to whether he commits his future at Parkhead or moves on.

Lewis Morgan – With James Forrest and youngster Michael Johnston ahead of Morgan in the pecking order, his chances will have dropped even further after the signings of Weah and Burke so a loan deal would allow the winger some much-needed game time.

A reunion with former boss Jack Ross at Sunderland has been mentioned but more recently it seems Hibernian have taken an interest so it looks as though Morgan will seal a loan move before the month is out.

Jack Hendry – After a difficult start to his Celtic career, Hendry is now the fifth choice at centre-back, therefore a loan spell would be beneficial for the former Dundee man and allow him to build his confidence in some less high-pressure games.

Once again Sunderland have taken an interest as well as Steve Clarke at Kilmarnock who may look to bolster his defensive options and work with Hendry.

Youssouf Mulumbu – Despite only joining the club in the summer, Brendan Rodgers has admitted that the 31-year-old, who signed a two-year deal, will probably leave for a loan spell in order to play more football having made just three appearances so far.

Dedryck Boyata – At the moment, the club seems content on letting Boyata run down his contract and leave on a free in the summer and refuse the temptation of cashing in now.

A new contract is pretty much dead in the water so unless any big money bids come in, the Belgian looks set to stay put till June.
