The Reds have been beset with injuries to defensive players of late, with Jerome Boateng, Medhi Benatia and Javier Martinez all being ruled out, leaving Holger Badstuber as the club’s only fit, recognised centre-back.

Tasci's arrival is a welcome boost for coach Pep Guardiola, whose side face a tricky run of fixtures that includes a trip to VfL Bochum 1848 in the DFB Cup on 10 February and a two-legged clash against Juventus in the last 16 of the UEFA Champions League on 23 February and 16 March.

'Quality and experience'

"We're happy to have been able to bring a player like Serdar Tasci to FC Bayern München at such short notice," said sporting director Matthias Sammer of the 28-year-old. "His quality and experience will be an immediate help to us."

The player himself was delighted to return to the Bundesliga after two and a half years in the Russian capital following his departure from VfB Stuttgart in August 2013. "I feel great and I'm really looking forward to this challenge. I hope to be able to help the team."

Bundesliga champion

Tasci, who has won 14 caps for Germany and will wear the number four shirt at the Allianz Arena, featured in 16 of 18 league matches for Spartak this season. He previously had a successful seven-year spell at Stuttgart, with whom he won the Bundesliga title in 2007 and captained to the final of the DFB Cup – losing to FC Bayern – in 2013.
