Gordon Strachan declared it still possible that Dion Dublin would be one of two players to arrive at Celtic before the season starts following the friendly victory over Everton.
Strachan is finding money for new players hard to come which is why he might have to bring 37-year-old former Manchester United striker Dublin back after finishing the season with them last season.
"I've no idea if we can get more players in but it could happen," said Strachan. "I have been trying to bring in players since I got here and for this season but have not been able to because of circumstances."
