Gordon Strachan is not expecting there to be too many more arrivals at Celtic before the transfer window closes.
German defender Andreas Hinkel has already been recruited from Sevilla but Strachan has yet to secure a deal for Bayern Munich centre-back Daniel van Buyten.
The Celtic boss has refused to rule out further transfer activity but concedes that he is not busy searching for new players.
"We've sealed one deal in Andreas. But we have not looked at too many more - there might only be one player who comes in," Strachan told the Celtic View.
"We've had loads to look at just in case and you have to be on your front foot in case there is a ridiculous bid for someone in your team.
"You always cover that and you continually look to find better (players).
"It's taken a while but we have Andreas and the good news is that Mark Wilson is coming back as well.
"In terms of him and other people coming back to full fitness, we should be all right for the season ahead.
"We might want to add one more but we will continue to be prepared in case someone moves out."
Scott Brown, who moved to Parkhead from Hibernian last summer, is looking forward to the rest of the season as Celtic step up their quest for silverware.
He has already played 35 games for club and country this term but insists he is raring for more.
"We've had a lot of games but now things are about to step up to another level," Brown said in the Daily Record.
"In my opinion, the more games you play the better you become. I'd rather it was this way.
"I like the expectancy and I welcome the pressure. That's one of the reasons I signed for Celtic."
Bjarnsson on the move
Celtic midfielder Teddy Bjarnason, meanwhile, has completed a permanent move to Norwegian club Lyn Oslo.
The Icelandic player joined Celtic in January 2005 but made just one appearance for the first-team before suffering a serious foot injury.
