Aberdeen manager Craig Brown has hit out at a section of the club's fans after they barracked new captain Richard Foster.
Some fans are unhappy that Foster spent last season on loan to Rangers.
"The only negative last night was the shameful abuse Richard Foster received from a small number of supporters," Brown said after a 2-1 loss to Bochum.
"Unfortunately, a few people were giving Richard a bit of abuse, which I thought was unjustified."
Foster, who had come through the Dons' youth system, was sent out on loan by previous manager Mark McGhee as part of a swap deal for Rangers striker Andrius Velicka.
But a permanent move to the Dons' Scottish Premier League rivals did not materialise and Foster was made captain this week by Brown after his return to Pittodrie.
And the manager insists that Foster is a popular choice in the dressing-room and that the fans who voiced their opinions at their Netherlands training camp are in a minority.
"I had the feeling they wanted the notoriety," Brown told his club website.
"They do not represent the rank and file of the Aberdeen support.
"I also think it had nothing to do with the fact Richard was given the captaincy.
"I do not understand the reason for. There is no rationale for it.
"He is a popular choice amongst the players and the staff at the club and the majority of fans. "
Meanwhile, Brown has revealed that none of his three trialists had done enough to earn a contract.
Swiss midfielder Edis Colic, 22, was previously with Nater in his homeland and was once on Thun's books, 23-year-old German goalkeeper Andreas Rossl was with Eintracht Frankfurt and 22-year-old left-sided compatriot Thomas Gentner was with Koblenz.
"They are good players but unfortunately not significantly better than what we have already got," explained Brown.
"We need to leave some slots in the squad for the next few weeks as we might get a loan or we might get a signing.
"There is still a lot of hard work going on to try and bring in new players."
