Former Spurs forward Clive Allen says chairman Daniel Levy is "not a football man" following the sacking of Tim Sherwood.
Sherwood's departure means Levy will now be seeking to appoint his his tenth manager in 13 years since becoming the club's chairman.
Speaking on BBC Radio Five Live, Allen said: "I don't think he is a football man. Those decisions have come back to haunt him.
"It's a very expensive squad and someone has to be answerable for that," said Allen.
Director of football Franco Baldini was the man who sanctioned the addition of £105m of talent in the summer, but a number of signings have disappointed this term and the Italian has survived much of the criticism from supporters.
"It's so bitterly disappointing the squad has finished sixth this season and the squad of players, in all honesty, are not competitive with the top four teams," continued Allen.
"A decision was made that a new direction had to be found and I just wonder what that direction is."
Southampton boss Mauricio Pochettino is now odds-on to succeed Sherwood with several bookmakers.
