Atletico Madrid goalkeeper Jan Oblak has hinted of a crisis at the club after defeat to Athletic Bilbao.

The result leaves Atletico's hopes of Champions League qualification in serious trouble.

Oblak lamented: "We started very badly and you can't start like that, with a hot head and insecure, so bad. If you start like that it's difficult to come back. We've had chances later, they've had a bit more luck, but they've been better and they've won.

"I hope we understand and can solve it. I don't understand it, in the locker room everything seems fine and then you go out on the field and in the 5th minute with two yellow cards and it gets complicated. I don't know where our heads are, but on the field today at the beginning... We can't do it that way. We repeat to ourselves that we have to do better, but if we don't do it, it's useless.

"I have no answer to what is happening. Since I've been at the club this hasn't happened and my teammates have personality and desire, but then on the pitch it doesn't come from us. I don't know what's going on. We have to improve, find the problem, because there are four games left and we have to reach the Champions League or it will be a problem."
