Chelsea may have to make signings to stop obvious set-piece weakness, admits Lampard

The Blues boss admits he has been aware of the defensive issue since before the season began, and he has done his best to counteract it

Frank Lampard believes his Chelsea players are simply not dominant enough in the air to defend or attack well at set-pieces, and they may have to address the issue in the transfer market.

Chelsea suffered a 3-2 defeat to local rivals West Ham at the London Stadium on Wednesday when Tomas Soucek twice had the ball in the net from set-pieces, with the first controversially ruled out by VAR.

The Blues have conceded the highest proportion of goals from corners in the Premier League this season, and although they have a higher average height than six other teams in the league, they appear to be the worst equipped to deal with set-pieces.
