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.
Paulo Sousa's agent has played down speculation that his client is looking for an imminent move back to England.
The Portuguese tactician is currently in charge of Hungarian outfit Videoton, but has previous experience of British football with Swansea, QPR and Leicester.
With both the Blackburn and Bolton jobs vacant, Sousa's name has been mentioned but his agent says he is more than happy with Videoton.
"I've read the news, that's all," Vladan Filipovic told Nemzeti Sport.
"It's not surprising that after the Europa League success he's linked with teams but it's not more than a gossip. I don't think it would be a reality that he leaves Videoton."
