Buttner admits he spoke to Van Ginkel about the Premier League before his summer switch.
"I immediately told him to go! I play every day against Nani, Antonio Valencia and Ashley Young and Van Ginkel battles with John Terry. Many people are already saying: this guy will be sitting on the bench and will not make it. Believe me: Van Ginkel is going to make it.
"They just need to give him time. It's nice to see that two guys from Vitesse ended up here," Buttner told Voetbalzone.nl.
