Spurs are thought to be eyeing up a move for the Steaua Bucharest centre-half, with the north Londoners said to be readying a £6.95m bid for the 23-year-old.
“He is a great player,” Piturca told Dolce Sport. “I hope he can establish himself in England with Tottenham.
“We have had many examples of players who have failed to establish themselves and have lost their place in the national team.
“It will not be easy, even if he is extremely good. I am sure he will be able to but it will not be easy because opponents in England are extremely good and must perform very well from game to game. His quality is tremendous.
“I want him to play well and bring that to the national team – we need to get good results this autumn to qualify for the World Cup.”
Piturca’s comments come after Chiriches’s agent Ioan Becali revealed that Tottenham are on the verge of signing the defender.
“I don’t know if there’s a deal with Tottenham but they sent an offer of £6.9m for Chiriches, which is what Steaua wanted,” said Becali.
“Steaua have to decide whether they agree or not. Steaua had offers of £6m and £6.5m but did not accept and said they only want £6.9m. Now the offer is on the table.
“I talked to the people at Roma [and] we were told that they cannot offer more than £5.5m or £6m, so we were allowed to talk to the people at Tottenham.
“Additionally, Tottenham are a good friend of mine. André Villas-Boas was in Bucharest a few years ago as my guest for a few days.
“Chiriches will not have trouble adjusting. He has been very well studied by Villas-Boas and his men told me that English football suits him better.”
