​​​​​​​Mauricio Pochettino says the VAR confusion in the first half of Tottenham's 6-1 FA Cup win over Rochdale was "embarrassing" and fears it could kill emotion in the game. Several incidents, both going in favour and against Pochettino's side, dominated the first half at Wembley, with referee Paul Tierney and VAR Graham Scott at Stockley Park regularly called into action on a busy night for officials. Spurs had a goal disallowed, a penalty awarded, and a penalty controversially disallowed through the use of VAR, with five additional minutes in stoppage time, and Pochettino is concerned the bizarre circumstances and confusion could kill the spontaneity and emotion in the game. He said after the win: "The first half was a little bit embarrassing for everyone. Difficult to keep focus and play football. I am not sure that the system is going to help. "Football is about emotion, it's a context of emotion if we are going to kill emotion in football. I think the fans of people who love football are not so happy about what they see today.
