Manchester United boss Jose Mourinho has aimed a dig at Manchester City forward Sergio Aguero ahead of Sunday afternoon's Manchester derby at the Etihad Stadium.

Aguero - City's record goalscorer - has scored 209 times in 306 appearances for the Citizens in all competitions.

The Argentine managed 100 goals in 230 appearances for Atletico Madrid before moving to England, meanwhile, and Mourinho paid tribute to the experienced striker's record in terms of goals.

However, the United boss has admitted that "there are little things" in Aguero's game that he is "not a big fan of".

"There are little things in Aguero's game that I am not a big fan of. I admire him because of his fantastic qualities. His numbers speak for themselves in terms of how many goals he scores," The Mirror quotes Mourinho as saying.

"And with Aguero, he hasn't just scored goals in one season. He scores goals throughout his career, and in a different league like the Spanish League. So he is a goalscorer who can score goals all over the world."

When pressed on what he did not like about Aguero, Mourinho responded: "I keep that for me".

Agüero has managed eight goals in his nine previous appearances against United.
