Vlasic showed signs of promise at Everton last season, but never really held down a place in their first team.
Silva decided that Vlasic should be loaned out, and his move to CSKA Moscow has already been a roaring success.
Vlasic has starred in Russia, and even scored the winner against Real Madrid in the Champions League.
The 21-year-old’s performances have suggested that he would have had something to offer Everton if he had stuck around at Goodison Park.
And if Vlasic now sees his future away from Merseyside that must be considered a blow.
Although Everton have good options going forward, Vlasic looks like he could develop into a serious threat at the top level, and Silva may be wishing he had shown some more faith in the Croatian now.
