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.
Ipswich have signed former Gillingham and Blackburn goalkeeper Jason Brown on a short-term deal until the end of the season.
The Wales international, 30, spent this week training with Town before penning the agreement on Thursday morning.
Brown, who made his name at Gillingham and Blackburn, has been a free agent since January, when an 18-month spell at Scottish club Aberdeen came to an end.
He arrives after Town's on-loan first-choice goalkeeper Stephen Henderson was last week recalled by parent club West Ham, bringing a premature end to his second spell at Portman Road this term.
Brown is understood to have been brought in to provide back-up for Scott Loach, who will now get the chance to prove himself.
