Celtic are looking to win their seventh Scottish Premiership title in a row, and will be looking to return to the Champions League group-stages.
Given how comfortably Celtic were in securing domestic dominance last season, it would hardly be a surprise if most were tipping Brendan Rodgers' men to enjoy another trophy-laden spell this term.
But with less than a month to go before the window closes, Rodgers would surely be wise to add to the three signings he has made during this window as there are arguably a few areas of the pitch where the Hoops need to strengthen further, especially if they hope to make more of an impact in the Champions League.
With that in mind, HITC Sport has taken a look at some of the areas Celtic still arguably need to strengthen and looked at some of the names who have been linked with filling those voids...
Celtic have a number of centre-backs currently, but their Champions League qualifier second-leg against Rosenborg highlighted that they perhaps still need further reinforcements with midfielder Nir Bitton filling in in the back four when Erik Sviatchenko had to come off injured. The Scottish Sun recently suggested that Steven Caulker was a target for the Hoops and talks had begun, but QPR boss Ian Holloway has recently suggested that he is delighted to have the one-time England international back in his ranks after the defender's struggles in his personal life, the Guardian reports, which would suggest that a deal is now unlikely.
With that in mind, Rodgers may be inclined to stick with the options he already has - especially with Bitton doing well in the role - but perhaps it may be a position the Hoops could look at if they spot another potential target.
Kieran Tierney is arguably the best left-back playing in Scotland, so strengthening that position may not be an immediate priority. However, with reliable understudy Emilio Izaguirre moving on this summer, providing more cover for Tierney may be a smart move from the Bhoys.
Jonny Hayes has been signed during the summer - and may also be deemed by Rodgers to be capable of being someone who can cover at left-back - but there is no question that replacing former loanee Patrick Roberts is a huge task. Roberts has been linked with a return to Parkhead, and Rodgers recently confirmed that he wants to bring the Manchester City man back, Sky Sports reports. With plenty of options available already, signing another wide-man may be more of a luxury rather than a necessity.
Last season, Moussa Dembele and Leigh Griffiths covered each other perfectly, with both men stepping up to the plate when the other sustained an injury. This season however, they have been sidelined at the same time and that has highlighted a potential issue for Rodgers if he does not make any further signings. Signing another striker would certainly become essential if Dembele moves on, which Sky Sports certainly believe is a possibility. Given the buzz around the Frenchman, it seems likely that Celtic will have plenty of funds to use to replace him if he does leave. Sardar Azmoun has been linked with being a potential Dembele replacement, The Scottish Sun reports, but Gianluca Di Marzio has suggested that a move to Lazio is close, so perhaps Rodgers will need to have some other targets up his sleeve.
