Leicester started off their campaign in wonderful attacking fashion but the Foxes have recently relied on strong defensive performances for their success, keeping nine clean sheets in their last thirteen matches.
Now goalkeeper Schwarzer has gone on to speak regarding Leicester's sudden improvement at the back and has stated that keeping clean sheets will be the foundation upon which the Foxes will build their success from now till the end of the season.
The 43-year-old Australian said: "Initially we were playing a lot more open football, we attacked whenever we had the opportunity.
"That was one of our strengths, the ability to counter attack very quickly, and that is still one of our weapons.
"But once we hit that first clean sheet of the season, it cemented the idea that keeping clean sheets is important and is a good foundation to build on."
