One player Celtic will not be looking to do a deal for is Aston Villa's Libor Kozak.
The Bhoys are comfortably clear at the top of the Scottish Premiership table, but they are determined not to rest on their laurels and want to make their squad even stronger.
Collins is keen for Celtic to add quality to every department at the next opportunity, but the assistant manager has suggested that Aston Villa’s Libor Kozak is not on their radar.
"Ronny went down and had a look at the game and of course he [Kozak] scored a couple of goals but there's nothing imminent,” Collins said.
"We're looking to strengthen all over to be honest."
Celtic look certainties to take home the Scottish Premiership title again this term, but they did good business in January last term and will want to be similarly successful this time around.
Ronny Deila’s side snapped up Gary Mackay-Steven and Stuart Armstrong in January 2015, and both of those players have become prominent members of the side’s first team.
One potential problem for Celtic in the upcoming transfer could be their inability to offer any player they do want to sign European football.
The Bhoys have exited the Europa League at the group stage, and that could make it harder to persuade potential signings to move to Parkhead.
