The Capital Weather Gang has the sweltering game-time forecast.

*One week until the UEFA Champions League final rematch between FC Barcelona and Manchester United at FedEx Field just outside of Washington, and the word I’m getting is that Lionel Messi will rejoin Barca for the start of its U.S. tour but his participation in the friendly hasn’t been determined. Barcelona is without several regulars for its preseason opener today at Hajduk Split.

*Ali Krieger, the starting right back for the U.S. Women’s World Cup team, hosted an online chat Friday and discussed her future, Brazilian antics and several other topics. She is leaning toward returning to the German league, where she’s played for 3 1/2 years, but doing so would make it more difficult for her to gain time off to play in U.S. friendlies and Olympic qualifying in January. Conversely, WPS’s future is uncertain and Krieger has strong emotional ties to Germany, her second home. I’ve heard that three WPS clubs are interested in Krieger.
