It's been a frustrating few weeks for Brendan Rodgers and matters have now only been made worse by the recent update on an injured Celtic player that he risked playing against Rangers before the international break.

Celtic sign Kelechi Iheanacho

Much of Rodgers' frustration has surrounded Celtic's transfer business. Their 0-0 draw against Old Firm rivals Rangers summed up the attacking problems that they still needed to address and, as such, Kelechi Iheanacho has since arrived. Joining back up with Rodgers for the first time since their Leicester City days, the forward desperately needs this move to go well.

The Nigerian was a free agent when Celtic turned his way, having been released after a disappointing spell at Sevilla. Now, at 28 years old, the Bhoys have handed him one final opportunity to get his career back on track.

Speaking to the club website after welcoming Iheanacho to his side, Rodgers told Celtic's official website: “I know Kelechi so well and what he can bring to the team. He is such a talented player, with great ability, athleticism and work-rate.

“I am sure he will love being at Celtic and I believe our fans will love what he brings. He has great experience and he is right in his peak years so he can be a great signing for us. I am sure he will make a big contribution to the team.”

The debate is ongoing as to whether the forward's arrival will hand Celtic the boost that they were looking for, but whilst that rumbles on, the Scottish champions have been handed an undeniable blow on the injury front.

Anthony Ralston injury update after Rodgers risked him

After dropping out of the Scotland squad alongside Kieran Tierney, Anthony Ralston is now an early doubt to face Kilmarnock. The defender was thrown in the deep end and risked against Rangers despite appearing to take a knock just days before in Celtic's Champions League tie against Kairat Almaty and Rodgers has since suffered the consequences of that decision.

Given that Alistair Johnston is already sidelined with a hamstring tear, Celtic now have themselves a mini injury crisis in the right-back spot. It begs the question as to why Rodgers would risk Ralston against Rangers in the first place.

The manager is certainly a fan of the defender, having told reporters at the end of last season: "Guys like Tony are really pivotal to the culture of this club. He doesn't play every single game, but he is probably one of our most important players here because of his history at the club."

Celtic now have just 10 days to get Ralston back fit and ready for the Kilmarnock game as they look to return to winning ways in the Scottish Premiership.
