Celtic boss Brendan Rodgers already appears to be looking for players who he could bring to Glasgow in January.
Celtic have shown signs of progression under Brendan Rodgers’ stewardship, but their failure to win a match in the Champions League shows that the Glasgow club still have a long way to go until they can claim to be a force in Europe.
And Nicholas believes that Celtic need to add a high profile attacking midfielder in January, to ensure that they keep moving forward.
“Celtic are a long way behind [in the Champions League],” Nicholas said. “They need to add another one or two players. I’d like to see them in January sign another creative player, a little bit of stardust, a player of stature.
“Celtic have to keep the incentive of being out of Europe, and keep Brendan on his toes by feeding him what he requires.
“I’m not asking them to go and spend £15 million, but I’m asking them if they want to become a big club. If they don’t, what will happen is that they will sell Dembele for a big profit.
“If you want to keep Brendan long term, you have to say to him that ‘we are building’. If that means having to top up the wages, so be it. It’s a big club and needs big players.”
Celtic have been accused of not spending enough in recent transfer windows, but they did provide Brendan Rodgers with some funds last summer.
Rodgers paid money to sign Moussa Dembele and Scott Sinclair, and the pair have both made a big impact at Parkhead.
Celtic are already on the look out for more possible additions that they could make in the upcoming transfer window.
The Bhoys have already been linked with Crystal Palace midfielder Jordon Mutch (Daily Record), as Rodgers identifies more talent who would enhance the quality of Celtic’s squad.
