US vs. England - March 28 at Wembley
If this does come to be, it means the US men will play Spain, Argentina and England in a two-week period ahead of their first World Cup Qualifier. Add this to the matches against Mexico, Sweden and Poland and the team will have played 6 of the top 25 in FIFA's rankings this year (with three of them on the road). Not a bad total.
As far as England, this match seems tailor made for David Beckham to earn his 100th cap. The Galaxy play at home on May 24th and then in Toronto on May 31st, so he could fly out on Sunday and then have a much shorter trip to return to the club by the next match.
This would be another fantastic get if it comes to be and might even end up on network television.
