Loads of Celtic fans are calling for Brendan Rodgers to stick with Cristian Gamboa at right back, after the Costa Rican impressed in his return to the side.After Celtic’s elimination from the Champions League last week, fans were furious with the frailties in defence.Jack Hendry and Kristoffer Ajer are facing a sharp learning curve, Kieran Tierney wasn’t at his best, but worst of all Mikael Lustig seems completely past it.The 31 year-old has been an excellent servant for the club, but he was quite simply a step behind everyone else in the defeat to AEK, and fans want Gamboa to nail down that right back spot.Rodgers has been hesitant to give Gamboa the place, as he feels the 70-cap international is less solid defensively than Lustig, but he certainly looked up to scratch in the win at Partick Thistle.[brid autoplay="true" video="278881" player="12034" title="Rafa's Pub Facts Kane's Kryptonite & London's Biggest Losers"]The 5 ft 9 in ace picked up two assists bombing down the right wing, something that Lustig simply doesn’t have the legs to do consistently anymore.The veteran Swedish international has clearly been the manager’s preferred choice at right back, but fans are all calling for the big change to be made permanent.You can find some of the best Twitter reactions down below…
