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.
West Ham manager Sam Allardyce has confirmed the club will not be extending on-loan defender Emanuel Pogatetz's stay at the club.
Austria international Pogatetz joined from German side Wolfsburg during January's transfer window on a loan deal until the end of the season.
Pogatetz has made only a handful of appearances with the Hammers though, mainly as a substitute, and Allardyce has decided he will not be looking to retain the 30-year-old.
Allardyce said ahead of West Ham's final Barclays Premier League match at home to Reading on Sunday, according to the London club's Twitter account:
"We've already said to Pogatetz thanks very much, he's been a fantastic professional but it won't be extended, and we'll decide on the others after the game."
