Essendon remains confident its players and staff won't receive anti-doping infraction notices despite persistent speculation they will be handed down.

With the Australian Sports Anti-Doping Authority investigation ongoing, there have been recent suggestions there is more to play out in the supplements saga, with sanctions still a possibility.

Club chairman Paul Little said that based on available evidence the club still believed it was unlikely infraction notices would be issued.

"I think it's fair to say you would never say never, however in discussions we've had with the various authorities that are at the centre of this issue, they've given me a level of confidence that it is unlikely," Little said on Wednesday.

"Just based on that, we're looking forward.

"Unlikely means unlikely. You don't know what new information may be forthcoming at some stage in the future … I guess based on what everyone knows at the moment, we're comfortable that there shouldn't be any problems.

"However, there could be new information.

"I think the reference in the press on the weekend that there are infraction notices on the way is simply incorrect.

"The AFL know nothing about that, we don't know anything about that and I'm not concerned about that at this point in time."

The Bombers remain in contact with key bodies including the government, ASADA and the AFL, but Little said they had not had contact with the World Anti-Doping Agency.

As the younger players started training this week with more experienced ones to come back on Monday, Little said the Bombers had to look ahead.

"We can spend a lot of time worrying about things that haven't happened; we'd rather be putting our time and energy into what needs to happen going forward," he said.

"The people that continually bring it up and fan the flames … that's clearly driven by other motives.

"I don't think they understand nor do they really care too much about us, however my view is at the moment we can't do any more than we've done and we must now look forward and plan for the future."

Senior coach Mark Thompson, who was fined $30,000 for his role in the debacle, said while the ongoing investigation meant nothing was certain, the Bombers had to focus on the pre-season.

"We can't be certain but we're not spending much time thinking about it," Thompson said.

"We're thinking about our training, getting this place [the Bombers' new training facility] operationally effective and efficient, getting the players back and getting them fit and playing better football and having a good year.

"We can't spend too much time looking backwards."

Coach James Hird was suspended for 12 months for his part in the supplements scandal.

Little said the Bombers were intent on making sure he didn't just see out the duration of his sanction but returned "a stronger coach" from it, with a number of initiatives underway with the club champion.

There is to be no official role for Hird during the suspension but the Bombers are determined to do all they can to ensure he emerges better from the enforced time out of the game.

Thompson said while he hadn't spoken to Hird recently, he was confident he would "get through this".

The Bombers announced air conditioning company Fujitsu General as the club's new co-major partner on Wednesday.

Kia Motors Australia will continue as the club's other co-major sponsor while True Value Solar will remain a sponsor at a lower partnership level.

Little said the Bombers planned on installing their new CEO to replace Ray Gunston either towards the end of this year or start of 2014.
