Former Tottenham striker Paul Walsh feels the momentum is with Spurs in the battle for a top four place.
Walsh admits the manner of the win over last year's champions will give Andre Villas-Boas' squad a big psychological boost ahead of a tough run in.
"The players will be able to draw strength from it and belief from it," Walsh said.
"They will say, 'We won't give up because we know we can turn it around'. Because they have done it against Manchester City, it will be in the memory bank for when they need it and they will need to be strong mentality in the business end of the season.
"Fourth spot gets you into a competition and it gets you a big amount of money."
