Bournemouth boss Gary O'Neil was unimpressed by Tottenham counterpart Cristian Stellini after their dramatic win.
The Cherries won 3-2 thanks to Dango Ouattara's 95th strike.
Stellini, who was part of previous Spurs boss Antonio Conte's staff, headed straight down the tunnel following the final whistle.
O'Neil told BBC Sport: “When we were on the wrong end at our place, I shook the opposition manager's hand.
“I was disappointed with them today.
“I thought to go straight down the tunnel and not shake hands was poor on their part.
“But it is what it is."
