Pep Guardiola hopes for best after Kompany's latest injury
EFL Cup: Swansea 1-2 Man City
Manchester City were left sweating on an injury to captain Vincent Kompany after he went off late in his comeback game against Swansea.
Kompany, who had not played since damaging his thigh in a Champions League semi-final against Real Madrid on May 4 and has experienced an injury-hit City career, departed during the dying seconds of the EFL Cup tie.
Goals from Gael Clichy and Aleix Garcia ultimately sealed the deal for City but substitute Gylfi Sigurdsson pulled one back for Swansea in injury time, after which Kompany departed down the tunnel.
City manager Pep Guardiola 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."
Asked if he had spoken with Kompany, Guardiola added: "No, not yet. (His performance) was good. It's not easy after a long, long time without playing. Defensively, he was so strong - he played really well.
"Hopefully, it will not be a big problem. We will have to wait."
City recorded their ninth successive win under Guardiola, seeing off Swansea 2-1 despite starting with a team that showed nine changes following last weekend's 4-0 win against Bournemouth.
Swansea, who have now gone four league and cup games without a victory, had their moments but the visitors had an extra touch of class about them.
They were also helped by second-half substitute Kevin De Bruyne's introduction as they moved into the last 16 three days before facing Swansea again, in the Premier League.
"(Garcia) played well, and I want to congratulate the young players. They played well," Guardiola said. "Fernando made an amazing effort, because he had been injured for the last two weeks. He played a fantastic game."
The pressure has cranked up on Swansea manager Francesco Guidolin, meanwhile, with former Manchester United ace Ryan Giggs linked to the job.
Asked whether he was feeling any pressure after the Swans' recent run of results, he said: "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."
