Manchester City manager Pep Guardiola returned to the team on Wednesday, more than three weeks after taking time off to recover from an emergency back surgery.

The club's social media account teased the return of their boss, posting a silhouette of Guardiola with the caption "Guess who's back?" on X, formerly Twitter.

The 52-year-old oversaw the squad's Wednesday training, with most of his players returning from international duty this past week.

Guardiola missed the last two games of Manchester City, and assistant manager Juanma Lillo took charge of the team during a narrow 2-1 away win against newly promoted Sheffield United on August 27 and a dominant 5-1 victory at home against Fulham on September 2.

Manchester City remains unbeaten in the Premier League for the current campaign, winning their first three matches.

The defending Premier League champions will face the in-form West Ham United on Sunday.

Pep Guardiola underwent emergency back surgery

Manchester City announced via a press release on August 22 that the two-time treble-winning manager underwent emergency surgery for his back in Barcelona.

Guardiola has been experiencing severe back pain for quite some time now, and neurosurgeon Dr. Mireia Illueca performed the procedure on the former FC Barcelona manager on the same date the press release came out.

The Spanish manager made his recovery and rehabilitation in Spain.
