We've already faced Steve Tilson's men at the Lane in the Carling Cup this season and needed a goal from Jermain Defoe deep into extra time to secure a 1-0 victory.
Now it's FA Cup time again at the Lane with the Shrimpers back in N17 for a fourth round encounter.
TICKETS AVAILABLE ON THE DAY
"They made it difficult for us in the Carling Cup and I'm sure it will be the same," said Robbie, who should skipper the side if he starts. "They are a decent side and they play good football - where they are in the Championship is a bit of mystery with how they play.
"It's a good draw for us in that we're at home and you want to avoid the Premiership sides, but having said that, it won't be easy for us.
"We all know the FA Cup has a great tradition here are we're all looking forward to it, an FA Cup tie is always a special occasion at White Hart Lane."
Robbie Keane expects a repeat performance from Southend at the Lane on Saturday - and that means another tough test.
