He told Celtic View: "We've sealed one deal in Andreas (Hinkel). But we have not looked at too many more - there might only be one player who comes in.

"We've had loads to look at just in case and you have to be on your front foot in case there is a ridiculous bid for someone in your team.

"You always cover that and you continually look to find better.

"It's taken a while but we have Andreas and the good news is that Mark Wilson is coming back as well.

"In terms of him and other people coming back to full fitness, we should be all right for the season ahead.

"We might want to add one more but we will continue to be prepared in case someone moves out."
