Tottenham threw away a two-goal lead as last season’s Champions League finalists were forced to settle for a point against Olympiakos in Greece.
Two goals in four first-half minutes put Spurs in control, with Harry Kane opening the scoring from the penalty spot before Lucas Moura’s scorching 20-yard finish.
Yet Mauricio Pochettino’s side conceded shortly before half-time through impressive Portuguese winger Daniel Podence’s quality finish.
That lifted the passionate home crowd and Olympiakos equalised from the game’s second penalty, former France forward Mathieu Valbuena beating Hugo Lloris, the current Les Bleus captain, from the spot.
The result means both of last season’s Champions League finalists have failed to win their opening group games, after holders Liverpool were beaten 2-0 by Napoli in Italy on Tuesday.
Sloppy Spurs fail to hang on again
Pochettino’s side showed Herculean spirit to go all the way to the final last season yet were far from their best as they made a shaky return to the competition in the port city of Piraeus.
Having allowed a 2-0 lead to slip against Arsenal in the Premier League on 1 September, this was the second time in three games they been left to reflect on what might have been.
With Bayern Munich and the unpredictable Red Star Belgrade also in Group B, Pochettino will hope this result does not come back to haunt his side.
Kane won the penalty which led to him breaking the deadlock, the Spurs striker clearly tripped by Tunisia defender Yassine Meriah,. Then Moura produced an emphatic finish after Ben Davies marked his return by winning back possession and laying on the pass for the Brazil winger.
On a frustrating night, Kane could have had a hat-trick.
Yet, on two separate occasions, Dele Alli – making his first start of the season – and substitute Erik Lamela decided to go for glory instead of choosing the easier option of squaring to Kane to score.
Tottenham are back in Premier League action at 12:30 BST on Saturday when they are at Leicester City, while their next Champions League Group B game is at home to Bayern Munich on 1 October.
