Jose Mourinho says he won't let his past rivalry with Pep Guardiola get in the way of his new career at Manchester United. With Guardiola taking charge at Manchester City, the pair will face off in the Premier League next season. They previously were adversaries when Mourinho was at Real Madrid and Guardiola at Barcelona. Mourinho says in Spain "individual battles make more sense because they can affect the outcome (of the title race). If in the Premier League I were to focus on him and Manchester City and he were to focus on me and Manchester United, someone else would be champion." Mourinho, who was at Lisbon University to give a lecture, says he won't be taking any player from Portugal to Old Trafford. Mourinho makes peace with Charlton Jose Mourinho made peace with Bobby Charlton as Manchester United's new manager met the Old Trafford icon at the club's Carrington training ground Monday. Charlton has previously been a harsh critic of Mourinho and was understood to have objected to his potential appointment when United was looking for a successor to Alex Ferguson in 2013. The 78-year-old, a member of United's board of directors, also criticized Mourinho in 2012 for poking Barcelona's assistant coach Tito Vilanova in the eye during a heated touchline clash, saying at the time: "A United manager wouldn't do that. Mourinho is a really good coach, but that's as far as I would go really. "He pontificates too much for my liking. He's a good manager, though." But, despite Charlton's criticism, United finally turned to Mourinho last week, hiring the former Chelsea manager after the failed regimes of David Moyes and Louis van Gaal. With Mourinho being taken on a tour of United's training base, it could have been an awkward moment when he met Charlton, but the 53-year-old Portuguese was keen to bury the hatchet. Mourinho shared a warm embrace with Charlton and, in reference to the United legend's goals in England's semifinal victory over Portugal in the 1966 World Cup jokingly told him: "You killed my country's dream in 1966 but even so, all the best." Charlton responded by saying: "I am very happy to see you here" before Mourinho told him to save the kind words until he starts winning matches. The video of the meeting, released on United's official website, will be seen as an attempt by the club to draw a line under Charlton's comments about Mourinho. Mourinho and long-time assistant Rui Faria joined Charlton, United's executive vice chairman Ed Woodward and head of elite development John Murtough on a tour of the club's training center. The former Real Madrid boss was also photographed by his wife Matilde's Twitter account in an image that showed him standing outside the training ground holding a club shop bag emblazoned with the United badge. Mourinho is scheduled to start work with those United players not involved in Euro 2016 or the Copa America when they report back for pre-season training on July 4.
