Jose Mourinho didn't just join Manchester United today, he also joined Instagram with a brilliant first (and so far only) post - of his United contract.

He quickly amassed 100,000 followers in an hour.

"Manchester United Football Club, Old Trafford, The Theatre Of Dreams," read the caption.

United appointed the Portuguese as manager on a three-year contract with an option to stay on until at least 2020, the Premier League club said on Friday.

The 53-year-old Portuguese replaces Dutchman Louis van Gaal whose two-year reign at Old Trafford ended on Monday when he was sacked two days after United won the FA Cup.

"Jose is quite simply the best manager in the game today. He has won trophies and inspired players in countries across Europe and, of course, he knows the Premier League very well, having won three titles here," United executive vice-chairman Ed Woodward said in a statement.

"I'd like to take this opportunity to welcome him to Manchester United. His track record of success is ideal to take the club forward."
