The visitors, who were forced in to making three changes due to injuries, were 2-0 down inside eight minutes and crumbled at the Tottenham Hotspur Stadium.
Sean Dyche's side have now conceded 11 goals in their last three fixtures. Here's how Dan Black scored the performances.
5. Ben Mee 4
Stood off Kane when inviting the Spurs man to fizz in the home side's opener and suffered an unfortunate ricochet in the lead up to Moura's finish. Caught the wrong side of Sissoko as the midfielder made it 5-0.
6. Dwight McNeil 6
One of the only players to come out with any credit from the defeat. Caused Aurier issues as soon as he switched flanks with Brady, which forced the full back to stick, and his deliveries deserved better end product.
7. Robbie Brady 4
Ineffective on the left and was soon ushered across to the opposite side. Went close as his header dropped down off the bar, but his distribution was poor, he was timid out of possession and was eventually replaced by Lennon.
8. Jeff Hendrick 4
The central midfielder was anonymous in his role alongside Cork. Failed to effect the game going forward and was meek and mild in the 50/50s. Went in halfheartedly as Son raced through to score.
