Di Matteo insists Clattenburg saga not affecting Chelsea players
Chelsea looked set to end a difficult week with a win thanks to Victor Moses' 61st minute header, but were denied by Pablo Hernandez's late equaliser, which also ensured Di Matteo's side surrendered top spot in the Premier League table to Manchester United.
Di Matteo said: "I wouldn't read anything into what has happened in the last week and the result today. It is very difficult to win away from home in the Premier League.
"This is our second away draw of the season - we have won the rest of the games. It is disappointing not to have hung on to our lead but even when you are not brilliant, you need to get a result like that.
"It's a long season and it is going to stay very tight at the top. There are a few teams fighting for that.
"We are in touch and we are going to show how strong we are in the future."
