Why have Chelsea slipped off the pace?published at 16:11 30 January

One win in seven Premier League games has left Chelsea off the Champions League pace, with last weekend's conquerors Manchester City leapfrogging Enzo Maresca's side into the top four.
After eight wins in a row, Chelsea have failed to keep a clean sheet since 22 December and watched as leads have ebbed away against Fulham, Crystal Palace, Bournemouth and Manchester City.
We have discussed the issues in goal already on Thursday - but what about the problems further forward.
Not helping matters is the form of Nicolas Jackson.
Two weeks ago, our Chelsea reporter Nizaar Kinsella outlined the striker's streakiness in a Blues shirt – regularly scoring in consecutive games before going weeks without netting again.
His inconsistency has been masked by Cole Palmer - an almost metronomic presence in front of goal who put Chelsea ahead in three of those games marked above.
But Maresca's talisman cannot do it alone and needs help from the supporting cast.

The above chart shows the number of goals scored by Chelsea's four most prolific players since the start of last season, with Palmer comfortably out in front.
Watching the timeline unfold (click here, external for the animation) is instructive. Palmer's leap into the lead was not inevitable. Indeed, it was not until almost midway through last season that he lit up.
As already established, Jackson's goals for Chelsea have come in clusters. One minute scoring four in three games, the next going goalless for seven matches.
And look at Christopher Nkunku. He barely featured last season but has arguably been a flat-track bully in the Conference League this season, continually plundering goals against Europe's lesser lights.
Yet he has not been backed to replicate that form in the Premier League and has been consistently linked with a move away from Stamford Bridge this month.
Meanwhile, last Saturday's goalscorer, Noni Madueke, is another to have flickered in front of goal.
He has 16 since the start of 2023-24, but once again - as the timeline shows - he has been unable to sustain his end product.
It is perhaps another reminder that youthful squads tend to struggle with inconsistency.
With the transfer deadline only a few days away, Chelsea continue to be linked with adding new options to their unreliable forward line.
Instead, Maresca may have to focus on bringing the best out of the options already at his disposal if he wants to turbocharge Chelsea's push for the Champions League.
