LONDON (Reuters) - Manchester United retained the Premier League title on Sunday when they won 2-0 at Wigan Athletic with a first-half Cristiano Ronaldo penalty and a goal by substitute Ryan Giggs.

United ended the season on 87 points, two clear of Chelsea, who drew 1-1 at home with Bolton Wanderers after an injury-time Kevin Davies goal for the visitors cancelled out a scrappy effort by halftime substitute Andriy Shevchenko.

It was United's 10th Premier League title and 17th championship in all and they will now go for a double when they face Chelsea in the Champions League final on May 21.

Everton qualified for the UEFA Cup after their 3-1 home victory over Newcastle United secured fifth place.

Birmingham City and Reading joined Derby County in being relegated after Fulham won 1-0 at Portsmouth to complete an unlikely escape.
