Spurs legend Alan Mullery said Chelsea should "face the consequences" if claims of an illegal approach for Tottenham's Frank Arnesen are true.
"Illegal approaches have been happening for years," Mullery told BBC Sport.
"It just goes on and on, and, as far as I know, hundreds of players and staff have been approached in this way.
"I'm sure Chelsea will appeal if any action is taken against them. But if they are found guilty then they should face the consequences."
Daniel Wynn of the Tottenham Supporters' Trust said he was left shocked after hearing the news of Arnesen's suspension after Chelsea's approach for the sporting director.
"I'm as stunned as everyone else," he said.
"It's one step forward and two back with this club at the moment.
"We'd had a much better season and there were signs of improvement.
"When Jacques Santini left in November that was a shock but there had been some mumbling that it could happen. This is a bolt from nowhere.
"It was the team to take us forward. Manager Martin Jol was Arnesen's man and he wanted him all the way through."
Former Tottenham player Gary O'Reilly told BBC Radio Five Live that Chelsea's financial clout is worrying for football.
"This will have very interesting reverberations not only around White Hart Lane, but the whole of football," said O'Reilly.
"What it does indicate, is that we have a situation at Chelsea where they appear to have the power to destabilise football.
"They have enough money to achieve any objective they wish. Maybe bringing in salary caps would help and prevent this from happening.
"It's now up to the Premier League to decide how they want to react.
"They cannot do anything until they find out how Spurs want to react - whether the club think the suspension of Arnesen is enough, or if they want to take the matter further."
