Eric Dier agreed Tottenham only had themselves to blame after a late collapse at bottom-of-the-table Southampton meant they were forced to settle for a 3-3 draw.
With 13 minutes to the final whistle, Spurs led on a comfortable 3:1, before Theo Walcott gave the Saints a hope to keep playing for, and the late Penalty converted by Ward-Prowse nullified Tottenham’ lead.
Dier speaking to Premier League Productions, accepted that Tottenham had only themselves to blame.
He pointed out sloppy mistakes made by the team, lost of possession at crucial moments, and poor defending which all led to the lost advantage.
The draw for Spurs on Saturday means Manchester United and Newcastle United continue to hold the upper hand in the race to secure a Premier League top-four finish.
Spurs are a point behind Erik ten Hag’s side having played two games more, while they lead Newcastle by just two points, despite the Magpies holding two games in hand.
