Tottenham Hotspur coach Les Ferdinand fears the club's bid to sign David Beckham could unsettle the dressing room.
Spurs are trying to sign Beckham, 35, on loan from LA Galaxy but Ferdinand has hinted that the protracted transfer could be more trouble than it's worth.
"There is going to be a mixed reaction from the players," Ferdinand told the Daily Star. "Some of them will look and say, 'What is this guy actually going to bring to us?'
"But I wouldn't say it's a PR stunt. Harry does genuinely believe David can bring something extra to the club.
"And not just on the park, because the guy is such a professional, a real example to others. It will be interesting to see how he trains and conducts himself.
"There may be some unsure what a 35-year-old is going to give the team, but his professionalism is not in question."
Although Beckham is currently training with Spurs, manager Harry Redknapp revealed on Friday that the club have only just received permission for Beckham to take part.
"We have only just got permission, it has just been agreed, that he can train with us today," Redknapp said. "There has been a bit of issue over that, so he has been joining in doing little bits. But they have now said he can join in today and join in with everything we are doing in training.
"I have had no conversation with anyone at LA Galaxy, so at the moment I don't think there is any progress on him playing."
Negotiations to seal a loan deal are ongoing with LA Galaxy, who insist their star player return to the USA for the start of the MLS club's pre-season campaign on February 10.
