Chelsea’s title? Five reasons why the Premier League race isn't over yet

Diego Costa: Has been key in Chelsea's title charge so far

Chelsea established themselves as Premier League favourites with their summer acquisitions, hit the front by winning their first four games and have led the way ever since. Is there any way back for their rivals? Adam Bate looks at the reasons why Jose Mourinho's men still have work left to do…

Perhaps it will require a sighting of Jean Van de Velde riding the ghost of Devon Loch around Stamford Bridge to convince anyone that Chelsea could possibly throw away the Premier League title this season.

However, with Arsenal and Manchester United joining Manchester City in the race for second, there are still three teams clinging on to slim hopes of catching the long-time leaders and the door has been left ajar just enough for fans of those teams to dare to dream.

From the reasons for Chelsea's unlikely dip in form to the unexpected hot streaks enjoyed by the Gunners and United, here are five reasons why – for now – there is some life left in this title race…

Faltering form

The familiar claim that it's not easy to turn form on and off ought to be a concern for Chelsea supporters as it's already cost them a tilt at the Champions League trophy this season. Mourinho's side have arguably failed to perform anywhere near to their best since defeating Swansea at the Liberty Stadium in mid-January.

Since winning on Boxing Day, Chelsea have picked up 22 points from 11 games – respectable enough but if that continues over the next seven games then Manchester City, Arsenal and Manchester United would each be mathematically capable of taking this race down to the final day.

Home hiccups

Surprisingly, where Chelsea's wobble has been most evident is at home. Mourinho's record at Stamford Bridge remains remarkable but chinks have been appearing of late amid the understandable atmosphere of expectancy. The Blues have won two of their last seven home games in all competitions and that includes an extra-time triumph over Liverpool in a game that was goalless after 90 minutes.

Burnley and Southampton have both held Chelsea in recent weeks and with Manchester United and Liverpool still to visit Stamford Bridge, their record in front of their own fans will be tested to the full before the season is out.
