Jose Mourinho's reign at Manchester United is well and truly under way.
Three months on from his arrival at Old Trafford and the Portuguese has made his mark having spent in excess of £150 million on summer signings, won the Community Shield and claimed three-straight Premier League victories.
Such is Mourinho's winning pedigree that it comes as no real surprise that United are currently top of the Premier League, level on points with Chelsea on nine.

A winning mentality has returned to the 20-time Premier League champions following three disappointing years since Sir Alex Ferguson retired.
This was evident against Hull City, with Marcus Rashford scoring a late, late winner after United refused to settle for anything less than victory.
But their win came at a cost - and a pretty big one at that.
Marouane Fellaini has discovered a new lease of life under Mourinho and performed brilliantly at the KCOM Stadium but, according to United's manager, he suffered a 'bad' injury against the Tigers.
Following his side's dramatic win, he said: "I am going to lose Fellaini for a while. He has a muscle injury in his back and it is not good."
It's expected the Belgium international will be out for up to a month, which also means he will miss United's clash with local rivals Manchester City on September 10.
Mourinho will now likely turn to Morgan Schneiderlin to partner Paul Pogba in central midfield, which is by no means a bad thing considering the Frenchman's quality.
Despite the setback, the former Chelsea boss was happy to have claimed all three points and revealed how his half-time team talk breathed life into United's players.
"I was expecting a difficult match and a tough time," he added. "I told them we were playing against a very well organised wall with an amazing spirit with everybody fighting for every ball and we couldn’t give them rest time.
"We couldn't play in glimpses. It had to be intense, intense, intense. We did that very well because every time we lost the ball we recovered it two seconds later and they had no chance to rest.
"But I told them at half-time that in the training session on Wednesday they were faster and more aggressive than they were in the first half today.
"On Wednesday I had to stop the session because it was too much. I said give me that in the second half."
