Mourinho says he is determined to improve United's squad, but has ruled out a major transfer splash.
“We are not going to spend more than we can. We are not going to do anything crazy," the United boss said.
“We are just trying to improve a little bit more. That's what we are going to try.
“Everybody will try to improve — like we did from last season. Last season we finished sixth and this season we are going to finish, hopefully, second.
“Next season, we are going to try to improve, but let's see what happens. Maybe also City will invest massively and they don't let the others close the gap to them, I don't know.
