Tottenham goalkeeper Paul Robinson has questioned the club's decision to allow England international midfielder Michael Carrick to move to Manchester United this summer.
Former West Ham star Carrick sealed a transfer to Old Trafford last month that could eventually be worth £18.6million but Robinson fears Spurs could regret the decision to let him leave White Hart Lane.
"If we want to break into the top four, we shouldn't be selling to the top-four group," he told the News of the World.
"Maybe Chelsea can afford to do it but you don't see United and Arsenal selling to each other.
"Financially it was good business for the club - providing the money goes back into the team.
"If we lose a player of Michael's importance, it must benefit the areas that need strengthening."
Spurs have lost two of their opening three Premiership games of the campaign.
