Nice and sporting by Moyes I suppose though that having an outfield player in goal wouldn't be in his team's best interests. This match would have been arranged with the intention of providing a stern pre-season test for his players, having an emergency 'keeper isn't really going to help his strikers hone their sharpness and the States is a long way to go to let a match turn essentially into a training ground exercise.
However, from the MLS point of view a golden chance has been missed. There is no better thing in football than an outfield player in goal, and seeing a nervous looking midfielder standing between the sticks in an ill-fitting goalie shirt would surely whet the American appetite for pinko commie Euro soccerball. Forget hosting the World Cup, forget American players proving themselves in Europe, forget even the arrival of David Beckham if there was one thing that was going to get the US to cast aside their shiny helmets and don Accrington Stanley shirts this was it.
While I'd agree that these transfers don't leave Arsenal quite as weakened as some think, the fact does remain that they do need an injection of new talent, that midfield spot you mention being a key position. Wenger must know this, but again it looks like a new player won't be arriving in that position.
Let's face it, Arsenal need to be playing in the Champions League if only for the finances it brings in they've had some warning shots in the past few seasons but have managed to hold on to a top four position. Manchester City's new found wealth should be ringing some serious alarm bells at the Emirates, it's no stretch of the imagination to see them challenging Arsenal for their place maybe not this season perhaps, but certainly in the long term. Their rivals are strengthening considerably, Arsenal need to do so to otherwise they seriously risk being overtaken.
