Relegation-threatened Livorno have sacked Domenico Di Carlo after just 88 days in charge and re-appointed Davide Nicola.
Virgil van Dijk claims he knows nothing of interest from English clubs and is keen to prove himself in the Champions League with Celtic.
Former Hearts and Sunderland goalkeeper Craig Gordon has not called time on his career despite his ongoing battle against a knee problem.
The 30-year-old has been without a club since his Sunderland contract expired last summer and has recently been coaching at Irn-Bru First Division side Dumbarton.
Gordon only played one game last season but he has denied rumours he has already retired from football.
The Scotland international told STV: "People can say what they like to say but I'll continue to try and rehabilitate my knee and get myself in the best possible state.
"If that means I can get back to playing football then I'd be delighted.
"I've been round people in Europe and back home getting as many opinions as possible to find the one thing that will help."
