Jordie van der Laan told his manager he was too ill to attend training on Tuesday, April 30, before jumping on a plane to the UK capital.
The 25-year-old’s plan fell apart when television cameras picked him up in the crowd at the match between Tottenham and Ajax.
Ajax triumphed in the first leg before Tottenham staged a remarkable comeback to win in Amsterdam and reach the final.
“We wish Jordie all the success in the world and we separated with a handshake,” said Dutch team SC Telstar in a tweet.
The sacked footballer has been making the most of his free time: by trying to get a ticket for yesterday’s semi-final second leg.
“Surely I deserve a ticket for Wednesday’s match now? After all, I am free,” he tweeted, before offering his service to Ajax’s opponents.
“If Tottenham is looking for an attacker, I am free,” he added.
