The January signing says they must start converting chances.
“It is a worry when we have chances and don’t take anything from games and that’s happened three matches in a row now,” said Graham.
“The fact we have created chances shows something is right, we just need to finish more of them off.
“If we weren’t creating chances and were getting beaten we’d be in trouble and it would be a problem. If that stays the same then there will be cause to worry.
“But I don’t see the case to worry just yet – and hopefully we can get a result next week.
“We are creating chances and one game we’ll probably end up giving someone a bit of a beating, but that’s just the way football goes.”
