Liverpool legend Jamie Carragher believes Arsenal have moved ahead of Chelsea as favourites for the Premier League title.
The Sky Sports pundit believes Arsenal's consistency puts them ahead of the Blues in the race for the title. Meanwhile Carragher has compared Chelsea to Manchester City in suggesting their away form has not been good enough so far this season.
Writing on his column for Sky Sports, Carragher said: "Chelsea, meanwhile, were my favourites to win the Premier League at the start of the season because of the Mourinho factor, but now you'd probably have to say Arsenal are because of the great form they have been in.
Chelsea have been a bit like Man City in that they are doing ever so well at home - a staple of Mourinho teams - but are not doing so well away, so that's an area I'm sure Jose will look to address."
Chelsea are currently four points off the pace at the top and sit on the same number of points as second placed Liverpool.
Jose Mourinho's side take on high-flying Southampton this weekend at Stamford Bridge and will be hoping to make up ground on the Premier League leaders as Arsenal travel to the Cardiff City Stadium.
Chelsea will be hoping to bounce back this weekend after a disappointing 1-0 defeat to FC Basel in Europe in midweek, meanwhile Arsenal will be hoping to make it three straight wins in all competitions this weekend.
