The Blues have won their last 12 games on the spin to build a six-point lead to second-placed Liverpool.
Antonio Conte has largely kept faith the same starting XI during their excellent run of form.
“If they were to pick up just one or two injuries… it might affect them”
But former Liverpool midfielder Redknapp reckons an injury-crisis could doom their title bid.
“I’ve just got this feeling that might be the game that turns it all around for them.
“Because they are in great form, we all know it, but the one thing when I look at the squad, is that they perhaps don’t have the depth the other teams do.
“If they were to pick up just one or two injuries, maybe to Costa, it might affect them.
“But overall, they have been fantastic. Conte has done a great job. Hats off to them.”
