"Matic was a big player for Chelsea last season and even though they have sign players to replace him, he is going to be missed and possibly just as significantly, he strengthens Manchester United, there is no doubt about that".
The former Chelsea and Porto boss has a odd relationship with medals, and has often been seen to give them away to fans, even when they're Premier League winning medals.
Since then, United have splurged in the transfer market, spending almost £150m ($194.8m) on the likes of Romelu Lukaku, Nemanja Matic and Victor Lindelof as they look to improve on their league table finish last season.
And the United manager has pointed out that his remarkable record of winning the domestic title in the second season at his previous clubs offers no guarantees that the trend will continue this term. After a first season of transition, Mourinho must stamp his authority on this team and is under a lot of pressure to deliver the coveted Premier League title.
"Mourinho is a coach who likes more the ball practice, works the ball possession and makes short games", he added. "Old Trafford is waiting for us and I think Old Trafford has a reason to be behind us", he said.
"He had a good fight against two good central defender and I am happy with this period and how he fits into - I am never exhausted to repeat - an wonderful group".
"I just think that naturally, a manager in the second season knows the players and knows the club better".
"It is hard job to play against a team that dominates the possession - and he tried", Mourinho said of his striker.
As stingy as United's defence was last season - Mourinho's team kept the joint most clean sheets in the league with 17 - they can at times look really shaky at the back and will need to avoid conceding late goals. We'll take it step by step and be humble.
Jose Mourinho will be without Marcos Rojo, Ashley Young and Luke Shaw who are all still sidelined with injures.
"And we got a central defender that can play in many other positions, which is important". We lost only one league match at home and in the cups never lost (at home), but there were too many draws. The general feeling is that the two Manchester clubs will compete for the top prize, but I remain cautious at this prognosis. If we manage that, we'll try to finish in the top two.style="text-align: center;"
