Chelsea great Pat Nevin believes that the Blues' next two games, against Watford and Crystal Palace, are going to be challenging for the Pensioners, who cannot switch off in the Premier League.

The Londoners succumbed to their third loss in 18 league games as they were humbled 1-0 at home by Leicester City on Saturday.

And now as Maurizio Sarri's side prepare to play two away games in the space of five days before the year ends, Nevin believes that they are going to be challenging given Watford's form this season and Crystal Palace beating Manchester City in their last match.

While the 55-year-old concedes that Crystal Palace might not be able to carry on with that kind of form against other teams, he also insists that Chelsea will have to be prepared for a tough fight.

"There are two very challenging games coming up", Nevin wrote in his column for the club's official website.

"Watford are a stunningly strong and fit side who are exceptionally well-organised and Crystal Palace have of course just beaten Manchester City at the Etihad.

"Though I think it is unlikely that Palace will continue to score goals of that standard every week, they are both away games and therefore by definition in the Premier League, not easy."

The Pensioners are currently placed fourth in the table with 37 points from 18 games, level in terms of points with Arsenal, though they are ahead on goal difference.
