A former Liverpool and Tottenham star believes Sunday's meeting between the sides could define their respective seasons.
Paul Walsh thinks a victory for either team at White Hart Lane could be the stimulus for a top-four finish.
"It's a massive game for both my old clubs," Walsh said.
"Spurs are flying at the moment. It was a great fight-back to win at Arsenal last weekend and they were very impressive against Werder Bremen on Wednesday night.
