Bolton manager Owen Coyle reckons newly-appointed Chelsea boss Andre Villas-Boas will bring success to the Blues. He welcomed the former Porto manager, whom he knows from studying for their coaching badges together, to the Premier League and tipped him to be a hit at Stamford Bridge. Coyle said: "Villas-Boas is a tremendous addition to the Premier League. I know him well. I did my pro-licence with him and really took to him." He added: "He is a fantastic manager, who has achieved such a lot at such a young age. "He has so many attributes. He will be a great fit with Chelsea. There is no doubt he will be a huge success." Villas-Boas won the Europea League and the Portuguese title with Porto last season.
