Stamford Bridge was once a fortress. As a Chelsea fan, for much of the last 15 years, home games against lesser Premier League opposition were almost a formality. However, this season, home form is becoming a concern for Frank Lampard’s side.

Saturday’s defeat to West Ham was their first win at Stamford Bridge since 2002, and it is now just four home wins for the Blues in 11 games this season. That is a win rate of just over 36%, which is not good enough for a side who will be hoping to push for titles in the coming years.

These numbers are increasingly concerning when compared to the home league record of Jose Mourinho over both spells at Stamford Bridge. In 106 games at home across two spells, Mourinho lost just five games and won 79. This gave him a home league win rate of over 74%.

Although these numbers do not include other competitions, the difference in the home win rates is startling. What is perhaps more concerning for Chelsea is the inability to pinpoint the reason behind the poor form at the Bridge.

Lampard, Cesar Azpilicueta and Christian Pulisic have all been questioned on the subject, and none of them gave a specific reason. It seems unlikely that it can be a coincidence after this many games. Either way, Lampard will be looking to turn the home form around as soon as possible, before confidence issues begin to creep in.

The saving grace for Chelsea is the performances they are putting in away from home. The Blues have seven wins from 11 games on their travels and look like a different team at times when playing away from Stamford Bridge.

With several home games coming up, Chelsea must pick up more wins at home to avoid slipping out of the top four.

Some Chelsea fans are beginning to pick up on the poor home form. Here is some of the reaction on Twitter:
