Guardiola's men face the Swans tonight in the EFL Cup third round after being allowed to use Wales' Dragon Park facilities for training, says the Daily Star.
They then take them on again in South Wales in Premier League action this weekend as Guardiola's men look to maintain their perfect start to the season.
Guardiola has decided to base his squad in Wales for the week instead of making the long trip back to Manchester.
It is understood City coach Mikel Arteta helped arrange the training base through close friend Osian Roberts.
The duo did their coaching badges together in Wales and Roberts is Chris Coleman's assistant with the Welsh side.
