The former Spain forward, who scored 121 goals in 351 games for Atletico, worked in their academy last season as an assistant coach. He will be making the step up for the upcoming campaign.

‘I’m proud and happy to be returning home,’ he said. ‘It’s an exciting challenge I’ve got in front of me and we’ll give everything we can to continue to serve our club.’

Torres signed for the Blues in 2011 from Liverpool, which was a British transfer record at the time.

The attacker also scored 45 goals in 172 games at Stamford Bridge, including the famous goal at the Nou Camp to put the Blues into the Champions League final in 2012.
