The Celtic goalkeeper has been included in England's squad for upcoming World Cup qualifiers against Montenegro and Poland and Buffon believes he should be given the opportunity to replace Manchester City's Joe Hart in the starting line-up.
"I think it is time now for England to give Forster a chance," Buffon told The Sun.
"He has shown again in the Champions League what he is capable of.
"He made some big saves against Barcelona.
"He has proved he can handle the big games and the pressure situations. Now it is time to test himself at the international level.
"If the England coach is picking his team on form then Fraser is his only option."
