Peru are set to face Chile in two friendly internationals on March 30 and April 2, with both players wanted by their countries.
However the South American countries have an agreement with FIFA that European based players will not be called up for friendlies taking place outside of Europe.
So it seems that even if the players do receive call ups Sir Bobby will be able to prevent them from travelling if he plans to use either of them against Everton on April 6.
