Chelsea boss Jose Mourinho has said Arsene Wenger has a "dream job" at Arsenal and feels he should be challenging for more trophies with the players at his disposal.
There has been bad blood between the two managers for some time, with Mourinho famously suggesting Wenger was a "voyeur" in 2005 after the Frenchman made comments about his Chelsea side.
The pair even exchanged comments while Mourinho was away from the Premier League, and the Chelsea boss called Wenger a "specialist in failure" last year in reference to a trophy drought that stretched back to 2005.
Wenger ended that long wait for silverware last season when his side lifted the FA Cup, but the Chelsea boss said Arsenal should be achieving more.

"I do not understand why they are not where we are with Man City," he said during an appearance on Sky Sports' "Goal on Sunday" programme. "He has a dream job. I think every manager in the world would like to have the stability he has. Year after year after year, he has the chance to buy, to sell, to rebuild, to wait for success and wait and wait."
Mourinho said Wenger deserved respect for his earlier successes, having won three league titles and four FA Cups between 1997 and 2005, but maintained that the Frenchman had good enough players to achieve more.
"What he did with the club in a certain period gave him that credibility -- that he deserves because he is a fantastic manager, but he also had a fantastic situation to be successful," he said. "When I look at the players and I look at the squad, I really think they have to win.
"I like that team very much. They have very good players. Alexis [Sanchez] and [Danny] Welbeck are important players to add to an already very good squad."
