Victor Wanyama took to twitter to celebrate their win over Fulham.
Spurs reached the final eight of the competition with a comfortable 3-0 victory over Fulham, with Harry Kane scoring a hat-trick.
Pochettino's team selection reflected his desire for a positive result as he started with Kane, Dele Alli, Victor Wanyama and Christian Eriksen whilst bringing back Belgian central defender Jan Vertonghen for his first start since injuring an ankle last month.
Following the game, Wanyama celebrated the victory with a post on twitter.
He wrote: “Great Team performance today, on to the next round #FACup #COYS.” (COYS is the acronym for Come On, You Spurs)
