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.
Brighton have signed Cardiff's Craig Conway on a three-month loan.
Albion boss Oscar Garcia has moved for the Scotland winger after learning that Andrea Orlandi will be out for two months with a knee injury.
And Conway will be eligible up to and including the Championship game at Middlesbrough on December 14.
Garcia told the club website: "We were keen to bring extra options.
"With Andrea now ruled out for a longer period than we initially expected, another wide player became a priority.
"Craig is very experienced at this level and knows what it takes to be successful in the Championship.
"He can play on either wing, or up front as a second striker. He also has international experience and is a player who will improve our squad."
