Celtic manager Ronny Deila insists Virgil van Dijk does not want to leave the Scottish Premiership leaders in January.
Celtic boss Ronny Deila says keeping his best players will take priority over acquisitions in the transfer window.
Miralem Pjanic has told Roma he wants to remain at the club for the long term despite reports linking him with a move to the Premier League.
The Bosnia Herzegovina international has scored two goals in 12 league appearances to help Roma lead the Serie A standings.
The 23-year-old midfielder is a reported target of Manchester United, Manchester City and Tottenham as well as Russian side Zenit.
"I still have a year and a half left in my contract," Pjanic said in comments reported in Corriere dello Sport.
"Until 2015, I will probably remain at Roma. I don't know what will happen after that but we are discussing it.
"My intention is to remain here for a long time because I am happy. I don't exclude the possibility of one day playing elsewhere, but I doubt this will happen soon."
Pjanic joined Roma from French side Lyon in the summer of 2011 and has been a regular in Rudi Garcia's squad this season.
