Hope he gets some decent game time in at least 1 of the games. However more important for him will be training and being around players like Rooney for a week an hopefully feeling like he belongs at that level.
Also as cynical as it sounds a goal against Slovenia and good performance against Scotland would stick another £5m on his value straight away.
It's becoming inevitable he will leave (I can't see him going in January unless we get really stupid money though) so lets enjoy him while we can. Great news for us as a club, and this will also hopefully help us keep hold of the current crop coming through. I know Berahino is a year or 2 older but he is now odds on to be playing for England at the Euro's next summer whilst Brown, Dhanda and Sinclair will probably have 5 first team appearances between them for their new clubs.
