Wrapping up the Preseason - Arsenal

This is the first year I've been interested enough in soccer to actually catch the preseason games.  And, by and large, I am more impressed with them than I am with the NFL preseason.  However, they both have their issues: starters leave too early, too many substitutions, changing most of the team at the half, etc.  
Right now I'm watching Arsenal vs Salzburg, seeing all the young guns and, perhaps most fun of all, seeing William Gallas still tearing it up at right-back.  However, with the recent departure of Patrick Ljungberg to West Ham, I think the Gunners are in serious trouble.  The loss of Ljungberg leaves Arsenal without an experienced attacking midfielder.  Rosicky and Helb are both great options as attacking midfielders but both have joined in the last two years.  I love Wenger's desire to groom young players but without a strong leader in attack (such as Bergkamp, Robert Pires, Henry and Ljungberg, all of whom were critical members of the undefeated team of 2003-2004) Arsenal will find it hard to offer good service to their strikers.  Without a seasoned veteran pushing the ball forward, Arsenal will score fewer goals and chase in many of their games.  
If there is one thing Arsene Wenger has to do before the beginning of the season, it is to sign a big-name attacker to draw double-teams (like Henry did) and supply balls that lead to scoring chances (like Ljungberg did).  Arsenal will find it tough to stay in the top four in England unless the young stars can begin to live up to Wenger's high expectations.  There is nothing I'd like to see more than Arsenal taking the EPL title from Manchester United, but without a strong leader in attack, I don't think it will happen.  Who knows, maybe Hleb, Rosicky and Fabregas can step up and make Arsenal into the entertaining, finishing club that advanced to the Champions League final in 2006.  Here's to hoping.
