Manchester City left Swansea for their temporary Welsh retreat on Wednesday night hoping captain Vincent Kompany had not succumbed to another serious injury.
With City facing EFL Cup opponents Swansea back at the Liberty Stadium in Premier League action on Saturday, the league leaders have opted to remain in Wales.
And they can only hope for good news on Kompany, who went off in his comeback match.
Kompany, who had not played since damaging his thigh in a Champions League semi-final against Real Madrid on May 4, departed during the dying seconds of City’s 2-1 win.
Goals from Gael Clichy and Aleix Garcia ultimately sealed the deal but substitute Gylfi Sigurdsson pulled one back for Swansea in stoppage time, after which Kompany departed down the players’ tunnel as the home side pushed for an equaliser via a last-gasp corner.
City manager Pep Guardiola, whose side were handed a fourth-round trip to Manchester United soon after full-time, said: “The doctors are speaking with him and seeing what’s up.
“Hopefully, it will not be a big problem. We’re going to wait for the results from the doctors.
“(His performance) was good. It’s not easy after a long, long time without playing. Defensively, he was so strong – he played really good.
“Once they scored the goal, after I said: ‘What happened?’ They said that Vincent had gone to the locker room. Hopefully, it will not be a big problem. We will have to wait.
“If he’s injured, he’s injured. He cannot stay on the pitch.”
While City have reeled off nine successive wins under Guardiola, Swansea are without a victory since August 23. Their next two games are against their EFL Cup conquerors and then Liverpool.
Swansea manager Francesco Guidolin said: “I am disappointed because I think we deserved another result. We deserved to draw and take it to extra time.
“The game was well-balanced and the performance of my team was good. It is not a good moment for us. Little things are going against us, we are missing chances.”
Asked whether he was feeling any pressure after the Swans’ recent run of results, he added: “It has not affected me.
“This is my job. With my experience, I know football is like this. it does not bring any added pressure for me. I have to work with my players, my staff and to pick up better results.”
