Tottenham are through to the semifinals of the Carabao Cup after a rare 2-0 win away against Arsenal on Wednesday night in London.
Both managers started strong XIs -- Son Heung-Min leading the Tottenham line with Harry Kane on the bench -- in a rematch of a Dec. 2 Premier League match which Arsenal fought back to win 4-2.
The in-form Son repaid his manager's trust on 20 minutes, lacing a left-footed shot past Petr Cech in the Arsenal goal after Dele Alli had picked him out on the counter-attack to give his team a 1-0 lead.
Moussa Sissoko should have made it 2-0 minutes later on another counter, but he fired over the crossbar after breaking free on goal from a Christian Eriksen assist.
Arsenal almost had a deserved equaliser before half-time, but Aaron Ramsey's first-time volley from an Alex Iwobi cross was somehow palmed off the post by Spurs backup keeper Paulo Gazzaniga.
The end-to-end action continued in the second half and Alli would double the visitors lead with a cheeky finish over Cech after being picked out by Kane, who'd only just come on as a substitute.
Arsenal were left to rue several wasted opportunities with Henrikh Mkhitaryan guilty in the first half, while the hosts also struck the woodwork on a couple of occasions.
Prior to the victory for Mauricio Pochettino's team, Spurs had won only two of their previous 30 matches at the Emirates and Arsenal's former ground Highbury.
Tottenham are looking to win their first silverware under manager Pochettino and their first since 2008 when they lifted the League Cup by beating Chelsea in the final.
