Celtic boss Neil Lennon believes some of his players will have benefited from being involved in the recent international fixtures.
The Hoops went into the international break following a 2-0 defeat at Hearts - a result that left them third in the Scottish Premier League.
Lennon's side are now ten points adrift of rivals Rangers after just nine games and go to mid-table Kilmarnock this weekend.
Celtic have a number of players in action for their respective countries at the moment, including Ki Sung-Yueng for South Korea and Daniel Majstorovic for Sweden, as well as players involved with the home nations.
Also away from the club is striker Georgios Samaras and midfielder Paddy McCourt and Lennon is pleased that those players have experienced the positive side of international football.
He told the club's website: "It can work both ways. If you get a negative result and come back, they always look forward to coming back and playing again.
"In Georgios' (Samaras) case, it's great for him to score for his country and it puts Greece in a really strong position in the group, so hopefully he'll come back full of himself.
"Paddy (McCourt) had a niggling injury there for three or four weeks and he was just starting to come back and featuring on our subs' bench, and the 90 minutes will have done him the world of good."
