The Chelsea boss says he is under more pressure than any other manager because "some have 10 years to win something" or "arrive on time to collect the fruits off their trees"
Mourinho arrived back at Stamford Bridge last summer but insisted towards the end of the 2013-14 campaign that his squad were not ready to win the title.
And now he feels he is under more pressure to deliver success than any of his colleagues.
"Why? Some have 10 years to win something, I have only two," he told reporters on Friday.
Wenger famously oversaw a nine-year trophy drought at the Gunners, ending with their FA Cup victory in May, but has not won the Premier League in a decade and was branded a "specialist in failure" by Mourinho last season.
The Portuguese then went on to hit out at other managers, perhaps old rivals Manuel Pellegrini and Pep Guardiola, suggesting they have benefited from good work by their predecessors.
“I’m not a very intelligent guy to choose teams,” he added. “I like to work. I like to build. I don’t like easy jobs. I don’t like to get clubs worked by other managers before me. I don’t like to arrive on time to collect the fruits off their trees.
“When I went to Porto, the season before they had been fifth. When I went to Madrid, where was Madrid? Where was Inter before I went there? And I came to Chelsea [last season] at a moment when one team was over and another needed to be born – and at the same time I came to the only league where four, five, six can compete for the title.
“At the end of the season you, the supporters and the players will judge my work. And most important, my boss, my owner, my board will judge my work.”
Pellegrini took over Manchester City last summer after the club had finished second and first in their previous two seasons, while Guardiola inherited Jupp Heynckes' treble-winning Bayern Munich squad.
