Tottenham hero Fernando Llorente enjoyed winding Arsenal fans after helping his team reach the Champions League semifinals.
Pochettino's side will host Ajax in the first leg at their new stadium on April 30 after dumping Manchester City out of the competition.
And Llorente liked a tweet poking fun at Arsenal's lack of European success since their move to the Emirates shortly after putting his side into the last four.
The tweet said: "Just a reminder that the Tottenham Hotspur stadium will have seen as many Champions League semi-finals within 27 days of its opening, as the Emirates has in its 13 year existence."
