Mesut Ozil fired a second-half hat-trick as Arsenal continued their unbeaten start to their European campaign as they brushed the Bulgarians aside.
Alexis Sanchez set the Gunners on their way to an emphatic victory to put Arsene Wenger's side in touching distance of reaching the knockout stages.
The Chile star gave Arsenal an early lead before Theo Walcott continued his scoring spree to make it 2-0 before the break.
Alex Oxlade-Chamberlain put them out of sight straight after the restart before Ozil stole the show in the second half.
Here's how they rated:
Ospina 8 - Alert when required, which was more often than you think
Bellerin 7 - Fastest defender in English __football but not yet the finished article
Mustafi 7 - Uncomfortable moments, frisky Ludogorets forwards kept him honest
Koscielny 6 - Stay awake at the back, concentration is not an optional extra
Gibbs 6 - Rude awakening if he was expecting a quiet night in
Coquelin 6 - Nearer quietly efficient than dazzling, but tidy enough
Cazorla 6 - Bright light that flickered but never quite burst into flame
Walcott 8 - Livelier than a beehive again, sensational finish to make it 2-0
Ozil 9 - MOM Floated through another shift like a ballerina in Swan Lake
Oxlade-Chamberlain 7 - Ox marks the spot: Clinical finish, almost back to his best
Sanchez 9 – MOM Chip, chip hooray: that finish to open scoring was simply divine
