Sir Alex Ferguson paid Jose Mourinho a visit at Chelsea's team hotel prior to their Champions League showdown against Paris Saint-Germain this evening.
The former Manchester United manager, who retired in 2013, was pictured entering the L’Hotel Du Collectionneur in Paris where he reportedly met up with the Special One.
The pair have maintained a close friendship having gone head-to-head on many occasions, starting with Porto's surprise Champions League win over Manchester United back in 2004.
Mourinho was tipped as a potential successor to Ferguson when he stepped down from the hotseat at Old Trafford however the Scot hand-picked David Moyes for the job. The former Everton boss lasted just 10 months in charge and was replaced by Dutch boss Louis van Gaal.
It is not clear as yet whether Ferguson will be at the game tonight. Chelsea will look to take a big step towards the quarter-finals of the Champions League when they take on PSG at the Parc des Prince this evening. The two teams met in the last eight last season and having fallen behind 3-1 in the first leg the Blues rallied to claim their spot in the final four.
Mourinho has confirmed that Diego Costa will be restored to the first team following his three-game suspension for a stamp on Emre Can in Chelsea's Capital One Cup semi-final against Liverpool, but he wouldn't confirm whether Thibaut Courtois or Petr Cech would start in goal - although it has been claimed today that it is the young Belgian shotstopper who will be handed the gloves.
Paris Saint-Germain meanwhile have endured a nightmare week in the build up to the game, stumbling to a 2-2 draw against Caen over the weekend while also losing four players to injury.
With the benefit of hindsight there aren't many fans who wouldn't go back at install Jose Mourinho as Manchester United manager when they had the chance. The Special One is spiky, obdurate and at times unreasonable but he's a born winner.
Given that Chelsea are playing in the Champions League 24 hours after Manchester United struggled to beat Preston in the FA Cup, it's now clearer than ever that the biggest mistake of Ferguson's career was not begging the Special One to take his job from him.
