A 1-0 win over the co-hosts for Roy Hodgson's men, coupled with France's surprising defeat to Sweden, means the Three Lions tackle Italy in the last eight in Kiev on Sunday.

And, though Germany do also block the path to reaching Kiev on July 1, Blokhin feels England could benefit.
"It is 50-50 against Italy," he said.
"If England had played against Spain, it would have been much harder.
"This is not the same Italy that won the World Cup (in 2006), so let's see how it goes."
