Sherwood, who took charge of Spurs in December, is expected to be sacked at the end of the season following a run of indifferent results.
Current Ajax boss Frank de Boer is reportedly in line to replace the 45-year-old at White Hart Lane, though Tottenham confirmed on Wednesday that no talks had been held between themselves and the Dutchman.
With Sherwood's future in doubt, Clemence believes that the former midfielder should be given more time to prove himself in North London.
"Wenger has been offered a new contract, everyone talks about how well Martinez has done, but everyone is talking about Tim - who has nearly done as well as they have towards the back end of the season - getting the sack. It really is a strange world we live in.
"All of us that have been involved want to see as many English coaches and managers being involved at the top clubs. There is an obsession at the moment that foreign is better."
Spurs are back in Premier League action on Saturday when they face West Ham United at Upton Park.
