Manchester United manager Jose Mourinho admits he is expecting a few surprises as he rotates the squad to help deal with a packed fixture list in October.
The Red Devils play six games in October, which also includes a break for international fixtures meaning they play five of those matches between 17 and 29 October.
The testing run of games include away trips to Liverpool and Chelsea, while they also host rivals Manchester City in the EFL Cup.
Mourinho's tenure at United so far can be best describe as up-and-down. They began in superb fashion by claiming the Community Shield and winning their first three Premier League matches in succession. However, they then lost three games in a row, but are now once again in the midst of a three-match winning streak and the Portuguese manager admits he still has a lot to learn about his players.
"You know, I need time," he said. "I need the players to play, I need to see them in different circumstances. I need to understand more about them.
"There is so much to learn about the players that only when you work with them a long, long time you really know them well.
"There's always a surprise behind the door when you work with a team for three or four or five months. There's always a surprise."
Mourinho also laughed off the suggestion that some fixtures carried more significance than others in the Premier League.
"You know every game is massive," he said. "You know, Watford was massive.
"We lost three points against Watford – not different from the three points we lost against Man City.
"So every game for me is important but, you are right, we have some big opponents in October but that's also a motivation."
