Pochettino said: "Yes (we deserved it), because if we scored in the first half, all the chances that we create, I think it was finished after 45 minutes the game. But, and then when we missed too many chances and then we concede in the way that we concede I think it was the emotional impact and we know very well the beauty of the of the cup.
"We saw yesterday different games like with Coventry. That is football, that is football, of course.
"But I think no one can say that we didn't deserve, I think we fully deserve to be on Wembley and we are in Wembley and the objective is to go again and for the second time, first was the kind of cup where we were in the final and now we are again in the FA Cup, you know, in the semifinal going to Wembley twice at the moment.
"Hope that three times we can go. But I think this group of players that will be a big credit and also the staff because in a circumstance that we are from the beginning of the season, I think it is massive to get twice. You know the possibility to fight for a for a title."
On Raheem Sterling missing a first-half penalty after taking the ball from Cole Palmer, Pochettino said: "No, I think, you know, very well that he scores but he gave the ball to Raheem. I think they have very good relationship that came from, of course, Manchester City, when they were both in Manchester City.
"I think when Raheem asked for the ball to take the penalty, I think Cole gave, you know, the ball you saw, you can see in the TV, but that is not a problem.
"Cole can miss, Raheem can miss, look for me, the decision is there and of course I'm going to support always, the decision of my players on the pitch. That is about to grow and be more mature and of course, always happy we take decision."
