Chelsea slumped to a 2-0 defeat to Leicester City on Tuesday night at the King Power Stadium and remained eighth in the Premier League standings.
Frank Lampard’s side have won just two of their last eight league games and the Chelsea manager has admitted that his team are struggling for results at the moment.
The Chelsea boss has been accused of tinkering with his team far too much this season and he has made 50 changes to his starting eleven in the Premier League campaign thus far.
Heskey conceded that the number of changes to the team are not helping the players as they are not able to build in any relationship with their team-mates and it is affecting their performance levels.
Asked about Lampard changing his team too much, the former striker said on Premier League TV after the match: “For me, that is one of the problems.
“As a player you want to play, doesn’t matter how many games, you want to play [in the same team].
“That consistency, the relationship you build, it helps you.
“When you keep coming out for one game, then going back in for two, but then you are coming out for three games, you are going back in for one, you can’t build up the consistency and relationship as well.”
Chelsea will next be in FA Cup action on Sunday when they will host Luton Town at Stamford Bridge.
Three days later Wolves will visit Chelsea in the Premier League.
