Perfectionist Pep Guardiola is still agitated by Manchester City's defending, despite winning nine from nine this season.

The Catalan gave his stars a rocket at half-time of Wednesday's 2-1 victory over Swansea City in the EFL Cup after surrendering a number of opportunities.

Guardiola - who saw Aleix Garcia score his first goal for the club - was not impressed with some passages of play, notably when surrendering possession in their own half.

City won 2-1 at Swansea in the EFL Cup in midweek - their ninth victory out of nine this term

But Guardiola still has concerns about the way his backline works, according to Gael Clichy

Gael Clichy, scorer of City's first goal, revealed the manager demanded more control of the game in south Wales.

'The boss wasn't really happy about this,' Clichy said. 'It's one thing to play against a better side who create chances but it's not good enough when you give them [opportunities] through losing the ball in the middle of the park.

'We know what we did right and we know what we did wrong. The victory was the most important thing and of course we can improve.

'We didn't start well - the first half wasn't good enough and then we started to play a bit better in the second half.'

City are waiting to find out the results of Vincent Kompany's medical assessments after he limped off with a suspected hamstring injury.

Kompany spent Wednesday with club doctors at Celtic Manor, their base for the week ahead of Saturday's return to the Liberty Stadium, as they attempt to diagnose the exact problem.

'I hope he is OK,' Clichy added. 'It was his first game back after a long period of time away. Hopefully it was more tiredness than anything else.

'We all know he is a great player and great leader so to have him back is a massive bonus for the team.'
