Celtic manager Neil Lennon is looking for "two or three" players to complete his squad ahead of the new season.
Lennon has downsized his squad with the likes of Daniel Majstorovic, Glenn Loovens, Mark Wilson, Efrain Juarez, Niall McGinn and Darren O'Dea moving on.
Lennon confirmed the number of players he was looking for and added: "We have trimmed the squad considerably. We don't want to make wholesale changes. We're always looking, if we feel we are getting a good player for value for money, we will always look at it."
Lennon does not have the challenge of Rangers or Old Firm derbies to sell the club to prospective signings but he feels the Champions League and the club's stature can attract targets.
South Korea international Ki Sung-yueng and Kenya midfielder Victor Wanyama have both been quoted this summer as saying they would like to test themselves in a more high-profile league.
That has clearly irked Lennon but he admits occasionally selling players for big money is part of the club's development plan. "I'm a bit annoyed because when players are on international business, they shouldn't be talking about club business," he said.
Lennon denied there will be more focus on Celtic's European campaign next season in the absence of Rangers from the Clydesdale Bank Premier League. A relaunched Ibrox club is set to play in the lower leagues with the Scottish Football League clubs meeting next Friday to decided on whether it is to be in the First Division or Third Division.
Without the traditional challenge from their Old Firm rivals, Celtic are overwhelming favourites to retain their SPL title next season and, ahead of the pre-season trip to Germany, Lennon insists that is his priority.
Asked if his attention will now be more on Europe, where Celtic face two qualifying rounds before the lucrative Champions League group stages, the Hoops manager said: "I'm not too sure about that. We are the champions and the most important thing is to retain the championship.
"Europe is something that we would like to progress in and take this team forward, and the club as well. We're preparing as best we can from Monday. We go away on Sunday for a 10-day training camp and we'll be working very hard to get the players up to speed."
