West Ham beat Tottenham a week ago and son of David Sullivan was glad to see their rivals suffer another defeat.
Borussia Dortmund at the Westfalenstadion are a formidable opponent, and Tottenham learned that to their cost on Thursday night.
Mauricio Pochettino fielded a weakened side due to a combination of injury, suspension, and simply choosing to rotate, and Dortmund made them pay, winning 3-0.
It was a disappointing evening for Spurs fans against a team boasting players who just three seasons ago were competing in the Champions League final.
It was the second defeat in eight days for Spurs, who lost their last away game 1-0 at London rivals West Ham.
Son of co-chairman David Sullivan, David Sullivan Junior, took to Twitter to express his pleasure at Tottenham's loss.

He did backtrack slightly, worrying about what the poor displays from English sides in Europe could mean in future years for the country's UEFA co-efficient ranking.
The performances of English teams in Europe is actually very worrying— DAVE SULLIVAN JNR (@DaveSulley) March 10, 2016
Italy only get three Champions League places and England four, but with Juventus reaching the final last season, the Italians are creeping up, while Premier League sides are failing to produce even in the Europa League.
West Ham are currently hoping to benefit from four spots available this season if they finish the campaign strongly, but whether they will have the same opportunity in future seasons remains to be seen.
The Hammers were in the Europa League earlier in the season after qualifying via the fair play table, but were eliminated before the group stages.
