"You're always going to get criticism here. If you're not top of the league there's something wrong and if you get knocked out of competitions then we're always going to get criticised," he continued.
"That's something that you just have to get used to. You can't sulk or moan about it, you've just got to get on with it and play good football like we have been doing.
"We've had setbacks throughout the years and you learn from them and they can help in a way. I've experienced that throughout my career - you might hit bad form or you miss a good chance, and you can't wait for the next game so you can rectify it.
"I'm sure all the lads felt like that after the City game and after the Basel game, which was a big disappointment too. You're going to get setbacks but it's how you react to them and thankfully we've come back strong."
