Carlo Ancelotti insists he still has belief in his system as league leaders Chelsea look to end their poor form away from home.
The Blues have turned Stamford Bridge into a fortress this season, with just one goal conceded since the opening day of the campaign but they are suffering on their travels, where they have lost their last two games.
Defeats at Wigan and Aston Villa temporarily blighted their good start under Ancelotti but victories over Atletico Madrid, Blackburn and Bolton at home have restored confidence in the 'diamond' formation.
Their 4-0 victory over Wanderers on Wednesday night was achieved without numerous first-team regulars. They will all return against the same opposition today for a game that will again test Chelsea's character and Ancelotti's system away from home.
“We want to maintain the same system,” said Ancelotti. “I said before that for this season, we follow this way at home and away.
“The last two matches away were not good for us, but we don't want to change because of that. I think this system is very good away from home.
“This will be a different game to the game in the Carling Cup. I think that Bolton can play different, but we want to play at the same level. We will pay attention to their quality, but we will put our best qualities on the pitch.
“Bolton will want to change something from Wednesday. We want to play the same, because we played well. We stayed compact over the 90 minutes, which is important against Bolton.
“To win this Premier League is a very long race. If it's possible to maintain being top of the table, as we are, then that's good.
“It means we've started the season well. But the race is very long and will only finish at the end of the season.”
