The Chelsea manager believes the length of the suspension is correct but feels the Liverpool striker should still be able to attend matches during his four months out
The Liverpool forward received a nine-match international suspension and a four-month global ban from Fifa for biting Chiellini during Uruguay's win over Italy on Tuesday.
Due to the stipulation of his suspension which prevents him from attending any football match, Suarez was not inside the Maracana as Uruguay were dumped out of the World Cup after being beaten 2-0 by Colombia in their last-16 fixture on Saturday.
"I think the punishment is deserved because it is an accumulation of [incidents where Suarez has committed] the same negative act on the football pitch,” Mourinho told Yahoo.
"What I really don't like in football is the stadium ban. What's the problem for Suarez to be in the stadium, in the middle of the Uruguay supporters watching the game between his country and Colombia?
"It's too hard, it's something that I really don't understand.
"If his punishment comes as a sequence of three similar mistakes in three different situations, it is something that he deserves. It has to stop."
