Chelsea boss Roberto Di Matteo wants Premier League improvement

Roberto Di Matteo says he wants to rival Manchester United and Manchester City in the Premier League next season after being named Chelsea's permanent manager on a two-year contract.

The Italian won the Champions League and FA Cup in 2011-12 as interim coach, but insists such achievements are now "history".

The appointment caps a big turnaround for Di Matteo, who left West Brom in February 2011 after a run of 13 defeats in 18 games.
