The summer transfer window has now closed, with Manchester City having again focused on bolstering their defence first and foremost.

Nathan Ake and Ruben Dias arrived for a combined sum of more than £100m, while Ferran Torres was another notable signing. Attention will now switch to the January window as Pep Guardiola's side attempt to win back the Premier League title.

Here, Sports Mole rounds up the latest news on possible comings and goings at the Etihad.

Monday morning's Manchester City transfer talk news roundup:

Jack Grealish 'becomes Manchester City's number one target'

Manchester City have reportedly identified Aston Villa captain Jack Grealish as their leading transfer target.

The 25-year-old was strongly linked with a move away from Villa Park over the summer, but he ultimately penned a new five-year contract with Dean Smith's side in September.

Grealish has been in brilliant form for his club during the 2020-21 campaign, contributing four goals and six assists in seven Premier League appearances.

According to the Daily Star, Pep Guardiola's side have been impressed by the attacker's development, and the England international has now become 'the main focus of City's attentions'.

Grealish, who is thought to be valued by Villa in excess of £70m, was believed to be a target for Manchester United over the summer after an impressive finish to the 2019-20 season.

The playmaker provided an assist in England's 3-0 win over the Republic of Ireland on Thursday night.

Manchester City 'want to bring Sergio Ramos to Etihad Stadium'

Manchester City are reportedly keen to sign Real Madrid captain Sergio Ramos on a free transfer.

The 34-year-old's existing deal at the Bernabeu is due to expire next summer, and as it stands, he would be free to agree a pre-contract with a foreign club at the start of 2021.

Madrid will allegedly make a statement on the central defender's future on Monday, and it has been suggested that an extension for the Spain international will be announced.

However, the speculation surrounding Ramos's future has not stopped, with both Juventus and Paris Saint-Germain said to be keeping a close eye on developments.

According to Argentinean journalist Gustavo Yarroch, City have also identified the former Sevilla youngster as a potential signing and want to bring him to the Premier League on a free transfer.

Ramos, who missed two penalties in Spain's 1-1 draw with Switzerland in the UEFA Nations League on Saturday night, recently scored his 100th goal for Los Blancos.
