Chelsea remain without a win in the Premier League this season after drawing 1-1 with Leicester City in their first home encounter of the season.
Frank Lampard’s homecoming saw for three changes from the heavy loss to Manchester United in N'Golo Kante, Olivier Giroud, Christian Pulisic, who all started in the UEFA Super Cup on Wednesday.
Mount robbed Wilfred Ndidi off possession seven minutes on the clock to finish past Kasper Schmeichel for his and their first Premier League goal of the season.
Big misses from close-range followed for the Blues in the latter stages of the half, with Mount and Kante the main culprits as the Blues gave Brendan Rodgers' charges hope.
The visitors put out all the effort in the earlier exchanges of the second half but for all their endeavour, didn’t bother Chelsea goalkeeper Kepa Arrizabalaga.
Giroud made way for Tammy Abraham 61 minutes in as the North London side instilled the evening’s first substitution.
Ndidi, who was hugely responsible for the opener, turned from villain to hero with a 66th minute near post header beyond Arrizabalaga following a corner kick, sending the visiting supporters into a frenzy.
The Foxes had their tails up in the final 20 minutes and Brendon Rodgers saw fit to give Denis Praet a league debut Minutes later, James Maddison scuffed a big chance with a miss from six-yards out after beating a host of bodies.
The Blues seemed unrattled as Willian blasted into the side-netting from a side-way pass whilst maintaining a defensive and offensive balance.
Belgian Youri Tielemans came close again for the visitors, but Arrizabalaga smothered the threat as the two sides settled for a share of the spoils.
