Jose Mourinho has told friends and associates that he will replace Louis van Gaal as Manchester United manager at the end of the season, according to reports in several British newspapers Wednesday. The Daily Mail, Daily Star, Daily Mirror and Daily Telegraph all quoted an unnamed source close to the 53-year-old Portuguese as saying his installation at Old Trafford was a "done deal." The former Real Madrid, Inter Milan and Porto coach was sacked by Chelsea in December but said in an interview last week that he would soon be back in management, preferably in England. Van Gaal, who has another year left on his contract after this season, has had to deal with constant speculation about his position after United made a stuttering start to the season. The Dutchman said Sunday he thought reports of negotiations between United and Mourinho were an invention of the media. 'No truth' in Chelsea rumors for Juve's Allegri Juventus coach Massimiliano Allegri has again distanced himself from the Chelsea manager's job amid claims he will replace interim boss Guus Hiddink at the end of the season. Allegri, who steered the Turin giant to the Champions League final last year, has a contract until June 2017 but is reported to be the Blues' number one choice to replace former Chelsea manager Jose Mourinho. Reports in England Wednesday claimed Chelsea owner Roman Abramovich had ruled Diego Simeone out of contention for the job because he does not like the Atletico Madrid coach's playing style. Although former Juventus coach Antonio Conte has also been linked to the club, the spotlight is firmly on Allegri due to his success with the club last season. But ahead of Juve's top-of-the-table clash against Napoli Saturday, he said: "There's no truth in it. I can't deny or confirm something that doesn't exist. "Once and for all, let's end this discussion." Allegri took over from current Italy coach Conte in time for the start of last season and led Juve to a fourth consecutive Serie A title, its first league and Cup double in 20 years and its first Champions League final appearance since 2003. Juve was outclassed 3-1 by Barcelona but its run to the final provided a huge boost for the club and for cash-strapped Italian football as a whole. Speculation that Allegri would soon quit Turin for London increased Monday when Giovanni Galeone, who coached Allegri at several clubs during his playing career and is described as his mentor, said Chelsea had made Allegri a "fantastic offer." "If I was Allegri, I would walk to Chelsea and I think he will end up there at the end of the season," Galeone said in an interview with Radio Radio. "He's performing miracles (at Juventus) considering that during the summer he didn't get any of the players he'd asked for. I think he will go to Chelsea because the offer is really fantastic." A win for Napoli would see Maurizio Sarri's league leaders open up a five-point lead over the Old Lady at the top of Serie A. But while currently in denial mode, Allegri appeared not to rule out a future move to England. Allegri added: "The thing that's fundamental for me right now is to get to the end of the season with Juventus and try to win some trophies, even though that won't be easy."
