Chelsea continued their perfect run in the Conference League thanks to a heroic performance from goalkeeper Filip Jorgensen following Christopher Nkunku's opener.
Both teams headed into this fixture with unblemished records across the opening three games - and it was clear to see why.
Paul Wanner had the pick of the chances in the first half after cannoning a shot towards the Chelsea goal but was denied by the strong hand of Jorgensen, in what would become a goalkeeping masterclass from both shot-stoppers.
Mudryk was convinced he should have been awarded a penalty after being sandwiched between two Heidenheim defenders but his appeal was denied - even after the referee was instructed to check the monitor.
Kevin Muller made five saves to keep Chelsea at bay before the break but could do nothing for Nkunku's opener, as the forward controlled the ball well and calmly slotted it into the back of the net.

His counterpart on the evening was also heavily involved and was the main reason the Blues held on to their slim lead following some wasteful finishing.
Jorgensen made 10 saves to keep his side ahead but was beaten on two occasions, only to be rescued by the offside flag each time.
Mudryk went on to seal the game with a stunning finish into the top corner to extinguish any threats of an upset - but the victory was slightly tarnished by a late red card for Cesare Casadei.
