Oh where to begin ...
Reina cost us quite a few points last year with errors where he was lacking in concentration - something you claim is part of 'stepping up for Liverpool.' He had a very poor 1st half, and was generally excellent in the 2nd half.
If you're calling him excellent based on his first few years, I'd say 100% agree. If you're calling him excellent based on the last few years, I'd say you've not been watching Liverpool much.
You make it seem as if Mignloet is some small time goalie - he shares time with Courtois (you know, the highest rated young goalie in the world - and the best goalie in La Liga last year) as Belgium's starting goalie ... 13 caps at the age of 24 ain't bad for a keeper ...
I'd say Reina is #2 for Spain based more on reputation than form - then again, so is the #1 keeper (Casillas, who barely played for half a season under Mourinho!)..
This move helps both sides. We're saving a shit load on his weekly salary, and bringing in a young, hungry international who may be ready to take his game up to the next level ... you know, like that 20 something goalie we bought from Villareal. I remember someone wrote something along the lines it was relatively easy for him to look good playing for an average La Liga club who have left him watching most games with their footy. People didn't think he could step up and play for liverpool, when there is always less action in your third, and demands more concentration. They were right, Reina was completely untested at this level ... he turned out ok.
