The Portuguese was content with Los Blancos' victory and played down the horrific weather conditions the players had to endure
In appalling weather conditions, Los Blancos snatched a 2-1 win at Ciudat de Valencia, thanks to a Cristiano Ronaldo goal and a late Alvaro Morata header, and the 49-year-old was happy with a hard-fought three points.
"We deserved to win but Levante made it very difficult, like they always do," he told reporters after the game.
"Both teams had to adapt to play in these difficult conditions, but playing in the rain is part of football. Levante reacted well. We had to give everything we had to win the game."
Mourinho was also quick to praise his match-winner Morata, but stressed the need for him to keep his feet on the ground.
"[Angel] Di Maria and Callejon were both fantastic. Morata is doing well but what is important is that he continues growing as a player and also as a person," he added.
The victory keeps Madrid in third position, five points behind Atletico Madrid and eight points adrift of leader Barcelona.
