How have Celtic's summer and January signings ranked this season?
Stuart Armstrong - B | The former Dundee United winger has impressed since joining the Bhoys but now it's about staying consistent and keeping his level up enough to make his mark on Celtic history.
Jason Denayer - A+ | Boss Ronny Deila has often emphasised the importance of the loan market and Denayer is an example of the perfect use of it. The 19-year-old Manchester City loanee has been superb.
Michael Duffy - N/A
Graig Gordon - A+ | Another fantastic signing. Celtic's two best signings have come either on loan or for free.
John Guidetti - B | The Swede has received a mixed response of late from fans as it is unclear whether he is willing to stay at Celtic on a permanent deal - the lack of contract negotiations suggests he isn't. But the striker has scored match-winning goals and that's what you want from a loan signing.
Gary Mackay-Steven - B | Just like Armstrong, Mackay-Steven has done very well since moving to Parkhead but the challenge lies in fulfilling his full potential.
Wakaso Mubarak - E | One of Celtic's unsuccessful recruitment ventures. The Rubin Kazan loanee just hasn't made an impact.
Stefan Scepovic - C- | Similarly, Scepovic has failed to make his mark on Deila's first team, although he has scored goals and played games this season.
Aleksandar Tonev - E | The final signing to grade but, unfortunately, not the best note to end on. Much like Mubarak, loanee Tonev will surely be sent back in the summer.
