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.
Sascha Riether has committed his future to Fulham by signing a new contract that ties him to the club until the summer of 2016.
The German established himself as Martin Jol's No 1 choice at right-back last season, while on loan from Cologne, and he signed a permanent deal back in May.
Riether, who was named player of the year by his team-mates, played 39 times in his first season in England and grabbed his first goal in their 2-2 draw with Sunderland in March.
"I'm happy to have got the deal done," Riether told Fulham's official website.
"I like it here - I love Fulham, I love the fans, I love the club, and I'm happy that we could close this deal now. It's the start of the season and we are well prepared so I'm looking forward to the future."
