I'm looking forward to seeing the back of Luongo now, his heart has clearly been elsewhere since the Asia Cup and I've a feeling we'll be seeing a reasonable amount of business in fairly quickly too. Power has his targets and will want to pin them down.
I agree he hasn't been the same player he was before he went, but think about it like this. He has played this much football:
July 2013 - August 2013 // Pre-season training & friendlies
August 2013 - May 2014 // Full season with us playing almost every game
May 2014 - July 2014 // Socceroos training & 2014 World Cup
July 2014 - August 2014 // Pre-season training & friendlies
August 2014 - January 2015 // Season with us playing almost every game
January 2015 // Socceroos training & 2015 Asian Cup playing almost every minute
February 2015 - May 2015 // Season with us playing almost every game including play offs
He's 22. That is a shit tonne of football. Regardless of how fit you think he should be because he's a professional, the human body does have limits. He's probably so burnt out. Don't be too harsh judging him.
