LONDON - Chelsea boss Roberto Di Matteo blasted the officiating as Chelsea suffered their first league defeat of the season in a 3-2 loss at home to Manchester United and their second in a week following their midweek Champions League reverse at Shakhtar Donetsk.Di Matteo is adamant there was contact between Fernando Torres and Jonny Evans and believes the Manchester United defender should have been sent off as he denied the Spaniard a goalscoring opportunity.After the Blues had overturned a two-goal deficit, they were reduced to nine men when first Branislav Ivanovic was dismissed before Torres received a second yellow card for diving following Evans’ challenge."The key decisions from the referee today probably influenced the result,’’ said Di Matteo. "He sent off Fernando Torres and the third goal is offside and it clearly has decided the game."So it’s a shame, because it was a good game of football with two good teams and the officials ruined it."He’s (Torres) put the ball between his legs and is through and gets a kick on his shin and he goes down. It’s a free-kick for us and I think it should have been a sending off for Evans because he’s through to the goal. Everything went for United and that really makes us unhappy.
