Manchester City are prepared to go back into the transfer market in January if Pep Guardiola wants to add a significant signing to his squad, a source has told ESPN FC.
Guardiola brought in five new faces in the summer -- Ilkay Gundogan, Nolito, Leroy Sane, John Stones and Claudio Bravo -- with a further three new signings -- Aaron Mooy, Oleksandr Zinchenko and Marlos Moreno -- all sent out on loan.
City's forward line will be further supplemented in January when Brazilian 19-year-old Gabriel Jesus completes his switch to the Etihad Stadium from Palmeiras.
However, a source has told ESPN FC that City will not hesitate in spending again when the transfer window opens if Guardiola feels he needs to strengthen his squad further.
The Catalan could potentially add another central midfielder with Yaya Toure not being considered for the first team until his agent Dimitri Seluk apologises for comments made about the coach and with City heavily reliant on Fernandinho.
There is also uncertainty surrounding the future of City captain Vincent Kompany after another injury setback, and the club has been linked with a renewed bid for Juventus defender Leonardo Bonucci.
However, Mahmoud, Vidal and Bonucci would all be unavailable for the Champions League knockout stages if they moved to City in January, having played in the competition with their current clubs this season.
Full-back is another position where City could potentially strengthen, although a source has told ESPN FC that they are not interested in Benfica defender Alex Grimaldo despite reports suggesting otherwise.
City have made only one January signing in the past five seasons -- the £28 million purchase of striker Wilfried Bony from Swansea.
