Pochettino said: That is football, that is the beauty of the FA Cup. First of all we really deserved to qualify for the semi-final."
On fans booing Sterling, he also said: "We need to support him, he's an amazing player. He has more than 10 years experience in the Premier League. Of course I think the contribution was good. He was a little bit unlucky with some actions where he should have scored. But we are a team and we need to be there for everyone.
"Fans are entitled to show their emotion. For us we try to emphasise with our fans not to criticise. They want the best for our team and players. But we are in a project. We need support and to really believe. We are trying to build something.
"We are in a process to build the team. I know really well how to manage. What the fans want is to win the game and that we achieved. What the fans want is to go to Wembley and that we achieved. They need to trust me to manage in the way I think is the best way for the club.
"We need to respect their opinion as much as they need to respect my decision."
