Brendan Rodgers insists Leicester remain “super underdogs” in the race for the top four after their draw with Chelsea.
The Foxes remain third in the Premier League and eight points clear of the Blues after Saturday’s 2-2 draw.
Antonio Rudiger scored his first Chelsea goals since October 2018 with a second-half double.
Harvey Barnes and Ben Chilwell cancelled out the defender’s opener before he struck again to level in the 71st minute during a frantic second half.
Lampard also dropped Kepa Arrizabalaga for the first time in the league this season after Kepa’s inconsistent form, bringing in Caballero.
He added: “No decision is easy. When it comes to goalkeepers, you probably do give it more a little more thought and time, especially with someone who is designated number one.
“But that can’t be the end of the story. We have to be competitive.”
