Tottenham Hotspur manager Mauricio Pochettino has admitted the 0-0 draw with Sunderland has left him disappointed.
As Premier League title rivals Liverpool and Chelsea played out a 1-1 draw, and Arsenal lost 2-1 to Watford, Spurs had a great chance to improve their position in the top four.
Instead, they failed to penetrate a miserly Black Cats side at the Stadium of Light, leaving the Argentine boss to rue a missed opportunity.
Asked if he was frustrated, Pochettino said: "Not frustrated, disappointed. It was a massive opportunity to reduce the gap to Chelsea and be in second position which was important for us.
