Chelsea's defensive strategy has come under fire following a 3-0 defeat to Brentford, with former captain John Terry calling for a major tactical change. The loss, which leaves the Blues winless in three games, has intensified pressure on manager Xabi Alonso. Terry specifically criticized the team's set-piece defending, highlighting vulnerabilities exposed during the match.

Terry, now a vocal critic from the sidelines, has urged Alonso to abandon zonal marking in favor of a more traditional man-marking system. This approach, he argues, would better counter opponents' set pieces and improve overall defensive cohesion. The criticism comes amid a slow start to the season, with Chelsea struggling to find consistency in both attack and defense.

Alonso, who took charge of the club in June, has faced growing scrutiny over his tactical decisions. The Brentford defeat marks another setback in a challenging campaign. While the team remains in the race for European qualification, the need for immediate adjustments is clear.

The pressure on Alonso is mounting as supporters demand results. With key players still recovering from injuries, the challenge for the manager is to adapt quickly and restore confidence ahead of crucial fixtures.
