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.
Crystal Palace youngster Kyle De Silva has expressed his delight after signing a new long-term contract at the club.
The 18-year-old has been handed a three-year deal with the option of a further year after breaking into the first team this term and making seven appearances.
De Silva is a product of the club's thriving youth system and made his debut against Derby earlier this year in the FA Cup.
He told the club's official website: "This is the club I supported as a boy so I was delighted to sign.
"I didn't really expect to make as many appearances as I did last season, I was training (with the first team) since Christmas so I got comfortable by the time I made those appearances.
"To start against Reading and Southampton were good experiences because they both got promoted.
"Now the aim is that first goal, trying to nail down a regular spot and (keep) working hard."
