Romantsev was the manager of Spartak Moscow from 1989 to 2001, during which time the club developed a technical short-passing game that won them eight Russian titles and one Soviet championship. The "Spartak style" also saw them make the last four of the Champions League, the UEFA Cup and the Cup Winners' Cup.
"It will be tough for Roman at Tottenham, as the club is not for him. They play a physical style of football with lots of battling," the 55-year-old trainer, who has recently returned to Spartak as trainer-consultant, told the Trud newspaper.
"That kind of football also has a right to exist - at an amateur level," Romantsev added.
Pavlyuchenko joined Tottenham from Spartak Moscow last summer, and has scored 14 goals in his debut season. He has however been unable to pin down a permanent place in the first team, and faces stiff competition from Robbie Keane, Jermain Defoe and Darren Bent.
"Pavlyuchenko is used to more technical football," Romanstev, who left Spartak before the striker joined the club, also told the paper. "[Andrei] Arshavin was luckier. He joined Arsenal, a club that plays in the Spartak style - technical, with lots of short passes and running and unorthodox moves."
Arshavin has had a big impact on the Premier League, with six goals and a similar number of assists in nine league games since arriving in February. His season hit a new high last week when he scored all four of Arsenal's goals in their 4-4 draw with Liverpool at Anfield, while Pavlyuchenko has struggled with an injury and has managed less than 45 minutes of football in Tottenham's last seven games.
