Jose Mourinho insists he will not look to reignite the rivalry between he and Pep Guardiola now the two are set to manage in England.

The Portuguese and the Spaniard were at each other's throats when they were in charge of Real Madrid and Barcelona respectively, forming fierce contests whenever the Spanish giants clashed.

Now Mourinho has been appointed boss of Manchester United, the personal feud could be set to continue in the Premier League, but the former Chelsea manager says he cannot afford to solely focus on Guardiola and his new club Manchester City.

"[What has happened in the past] does not allow me to be innocent," said Mourinho at a coaching conference in Lisbon.

"For two years Pep and I were in a league where the champion would be either me or him, Real Madrid or Barcelona.

"In a situation like this, individual fights make sense because they can influence things. But in the Premier League, if I focus on him and Manchester City, and he on me and Manchester United, someone else is going to win the league."
