Jose Mourinho, Manchester United and the Curse of The New Contract

It's been a good week for Manchester United. On Monday (January 22), they announced the arrival of Alexis Sanchez, snatched from the grasp of rivals Manchester City, and then on Thursday, Jose Mourinho, signed a contract extension.

United announced the new deal via Instagram to their 20 million followers, the news that Mourinho was due to stay on until 2020 was accompanied by the Portuguese manager beaming alongside executive vice chairman Ed Woodward. But history tells as the smiles won't last for long.

United is pleased with the progress the club has made under Mourinho. Despite being 12 points behind runaway leaders Manchester City, United is still second in the Premier League and has made significant advances from last season and from Louis van Gaal's era.

Mourinho has been backed by the club in the transfer market, with big-money signings in Paul Pogba, Romelu Lukaku and the arrival of Sanchez. United will expect Mourinho's team to be closer to City next season after the investment made over the past 18 months, but whether the Portuguese will be at Old Trafford at the end of the season leaves many sceptical.

At his last three clubs, Mourinho has signed contract extensions and been out of the door within a year. In fact, at Chelsea, he lasted just five months more. Mourinho put pen to paper over a new four-year deal in the August of 2015, rewarded for winning the Premier League title, and then he was sacked before Christmas as Chelsea lingered around the relegation zone.

A trend grows as we take a look at his job prior to Chelsea. At Real Madrid, Mourinho won the La Liga title, disrupting Pep Guardiola and Barcelona's dominance, and was given a new contract at the Bernabeu in May 2012. By May 2013, Mourinho had been sacked.

And so to Milan. Inter has always been the standout club on Mourinho's C.V., the one he left in tears, still loved by the masses after winning the treble. But the contract situation remains the same. In May 2009, Mourinho agrees a new deal with Inter and 12 months later he is gone.

The Portuguese coach insists Manchester United is different. He is settled in England and wants to create a dynasty at Old Trafford. Yet many would not be surprised to see him end up at Paris Saint-Germain soon.

Earlier this season, Mourinho was quoted by French TV as saying he had "ambitions" and didn't expect to retire at United. He then went on to speak effusively over Paris.

"The other day my son who lives in London went to Paris and not to Manchester to watch the match," Mourinho said. Asked why his son chose that option, the United manager added: "Because at the moment in Paris there is something special. Magic, quality, youth, it's fantastic."

The Mourinho trend has continued. It's now up to him, and only him, to break it.
