Mauricio Pochettino: "It was a shock because after that it all changed in this moment.
"Seven or six seconds before, all was happiness and there was good energy in the stadium. Our supporters were happy and believed that we would get a good result.
"But in this moment, I think it was difficult to manage in our head. Our heads had gone and we started to take rash decisions on the pitch.
"It was difficult because 12 or 14 minutes later, we conceded again another goal. At 2-1, it was difficult.
"It is not something where you can analyse the action, sort the tactical situation and move the players.
"With mentality, we need to work hard. It is not easy. We need to be more strong, like a team. This is our challenge.
"We need to speak, we need to create a different situation on the training ground and work.
"We know how but always you need to spend time to work in this area. It is not the same as in physical or tactical situations. It is a different area."
