Lorik Cana believes Sunderland must learn to deal with the level of expectation they now face going into games.
Having taken four points from a possible six in their last two matches against Manchester United and Liverpool many expected the Black Cats to continue their good form at lowly Birmingham.
However Steve Bruce's side fell to a disappointing 2-1 defeat at St Andrews leaving their captain questioning the mindset of his team-mates.
It is not the first time this season that the Wearsiders have raised expectations only to fall in the next game. Earlier in the campaign a 4-1 home win over Hull City was followed by a 3-1 defeat to Burnley at Turf Moor and Cana knows things must improve.
"It is very disappointing for us, but it's not the first time this season after some good results," he said.
"Especially when we have won at home sometimes, we can't keep our level of play - and we must turn that around in future games.
"Everybody knows the potential and quality of our team. But it's a hard league, and you have to be 100 per cent concentrated all the time and start well in games.
"We must learn from that and change our mentality to keep our level over two or three games.
"We have a lot of work to do."
