Mustafi said, "We dealt well with most of the things that were going on, on the pitch. I think we had opportunities and this was not the game we wanted, we didn't want a game that was open like this, going from one end to another. We wanted to have more control which is not always easy, we had to deal with a lot of long balls and to win the second ones, and, they're a team that does that well.
"I think we dealt well with that, but I think when we had the opportunities to break, we had a lot of space to attack them. I think that's where we could have done the second goal and the game would maybe have been a little easier. We have to continue, and go again and learn from every match we play."
He added: "I feel that we are united. I think we stay together and the dressing room has always been top during good and bad periods. That's the only way to get out of it and I think if we want to be successful, we need to stick together, players, staff and everyone at the club.
"Obviously all the people that comes to the games [too]. We want them to be happy but it's always good when a game like this finishes and you go round and applaud and they are [applauding] too, it shows that we are united. "
