Forest attempted to sign the Mexico international striker from Feyenoord before the transfer deadline closed but the 23-year-old turned down the move to stay and continue his goal scoring form.
Kraay Jr spoke on the move and why he thinks it was the right thing to do.
“People who have looked at it say that Nottingham Forest might be the level for Gimenez," Kraay Jr told Dutch magazine Voetbal International. “So then €25m is enough. But I think it’s smart of him not to do it.
“The boy scored 23 in the Eredivisie last year, but he lost it in recent months.
“I think Santiago is smarter. Who knows, against City, United, Arsenal, Liverpool and Spurs, he doesn’t even get one and a half chances per game.”
“Santiago will stay with Feyenoord, score more than 23 and play in the Champions League,” Kraay Jr added. “This is his right.”
