Perryman spent a short amount of time talking to his family on Tuesday.
"We're really desperately hoping for a very quick and early recovery," club trustee Roger Conway told

"His skills in negotiating the deals we've done, transfers in and transfers out are irreplaceable," Conway added.
Perryman is Tottenham's record appearance-maker, having played 866 times for the club between 1968 and 1986.
He held the record for most matches played in England's top flight, having played 613 times in the old first division, for 25 years
