"For large spells of last season, we felt we should have been higher up in the league than we were and performances certainly warranted that for large periods as well".
The 35-year-old was the only United player to get into double figures in the league.
"We have a central midfielder and striker, so obviously another player would be one coming from the sides".
"We always had more goals from wingers, midfielders getting 10 goals, central defenders getting five goals and last season that didn't happen much".
"It's to try to put them in a better position to win the title".
It represents a significant change for West Ham, who have looked overseas for many of their signings in recent years, with successes like Dimitri Payet offset by a number of failures in the window.
"So we have to disregard most of it, because it's something that we can't affect".
Guardiola will travel to Brighton with new signings Bernardo Silva, Ederson Moraes, Kyle Walker and Danilo, although Benjamin Mendy is still working his way back to fitness after a thigh injury. But he insists, despite that, the title is a more realistic target. "Sooner or later it's going to finish", he said.
"People say in the first news conference we are favourites".
"So yes we'll look at as many good experiences as we can do, and that's for the whole of the season, not just the start".
Instead, Mourinho will likely use either Jesse Lingard or Marcus Rashford on the left wing, with the former starting the UEFA Super Cup against Real before being replaced by the latter.
"But there's only one team that can win it and [Manchester] City brought [Pep] Guardiola to the club to win the Premier League and to win the Champions League, and he has to win something this year".
So for me I think Man City will miss out. Last season two were not.
"This time, we are all in the same basket".
"Some, okay, have the luck to play Tuesday or Wednesday, Saturday or Sunday, but in the end the same number of matches".
