LONDON — Brentford exposed Chelsea’s defensive problems to inflict a damaging 3-0 defeat yesterday that gives Xabi Alonso plenty to ponder over a three-week international break.

After a promising start to life under the former Real Madrid coach, Chelsea have picked up just one point from their last three league games.

Goals from Jaidon Anthony, Igor Thiago and Fabio Carvalho took unbeaten Brentford above their west London neighbours and up to third in the table.

Chelsea had quickly earned the reputation as the Premier League’s great entertainers under Alonso with their opening four games containing 19 goals.

But the loss of Joao Pedro to a knee injury subdued the Blues’ free-flowing attack as Cole Palmer and Morgan Rogers were comfortably kept in check by the Bees.

Alonso said after last weekend’s 2-2 draw against Hull he was hoping for more “boring” games going forward.

The Spaniard sought control as he made four changes in all, handing Jordan Henderson his first Chelsea start against the 36-year-old’s former club.

Alonso got his wish during a flat first half in which neither goalkeeper was seriously tested, but Brentford were the more threatening side in the second period.

The visitors’ frailty from set-pieces led to the opening goal when Jannick Schuster rose highest to meet Mikkel Damsgaard’s corner and Anthony was left with a simple task to head into an unguarded net just after the hour mark.
