But Coyle said: "We've a fantastic club, an unbelievable owner. The chairman and I have a great relationship.
"Our supporters have been great too. But I totally understand, given what we've done, the expectation is we have to be better than where we are just now.
"We have to improve. To do that we need the fans onside. I won't sit here and make excuses for myself or the group. We know we have to do better.
