Frank Lampard said Chelsea supporters have every right to be worried after they slipped to a fifth straight defeat under his management against Brentford at Stamford Bridge.

Cesar Azpilicueta’s own goal and a late breakaway effort from Bryan Mbeumo sealed a 2-0 win for the visitors and condemned Lampard’s team to a sixth game in their last seven in which they have failed to score as their faint hopes of finishing in the Premier League’s top half became increasingly distant.

After the latest defeat, Lampard said he has “no problem” with fans booing.
