Bruce said: "We are looking at one or two things. We are hoping that at least one of them will materialise. When I analyse the whole thing, with the work that we've done, I've been very pleased.

"If we don't get him, then we will have to look to someone else because that area of the pitch is where I am least covered at the moment."
Bruce is convinced Luccin would make a big impact at St Andrews should the £2million deal go ahead.
