Greg Taylor has fired a warning that Celtic are only going to get stronger once the new recruits get firing.
The defending Premiership champions have been on relentless form, dropping only five points in the league this season, and have a 100 per cent record at Celtic Park.
January arrival Alistair Johnston from Montreal has slotted into the side comfortably following the departure of Josip Juranovic to Union Berlin. But fellow arrivals Yuki Kobayashi, Tomoki Iwata - from the J-League - and Oh Hyeon-gyu, who arrived from Korean side Suwon Samsung Bluewings, are all being eased into Postecoglou's on-form line-up and building match fitness.

Taylor has been impressed by the incoming quartet and he's convinced they'll help the Hoops to even higher levels as they head into a crunch spell in all three domestic competitions.
Taylor said: "They've settled really well. You see Oh when he came on, he's a handful, he's young and eager and he's going to bring something to the party.
"Tommo and Ally have settled in straight away, Yuki too. They've all contributed already at an early stage and I'm sure that'll continue as the season. goes on."
Taylor, who bagged a third goal of the season in Wednesday's 3-0 win over Livingston, admitted that Ange Postecoglou's incredible strike rate in the transfer market leaves the squad with no doubts over the quality that comes in.
He said: "The manager has a clear philosophy so it's easier for the boys who come in because we've a set way of playing. We know they'll give 100 per cent, the mentality of the new guys is outstanding.
"Hopefully that'll be the case with any other new guys who come through the door. I'm sure they will have that too, they've settled well but we've lost boys who've done really well for us and it's important to be grateful for their contribution.
"But the new lads will be major contributors as the season. goes on."
