I've only seen him play full match (or close) when he played vs. Croatia. Was a disappointing game from him but he's only a kid.
Loan by all means. Those tend to work better for Real than for Barca.
In many matches, he has been fairly anonymous, with a few flashes of briliance here and there. And in a few matches he has shown that he could really become something special, doing things few at his age could dream to do, even on the national team has done things with the ball that the rest of our seniors couldnt hope to achieve, though Norways NT isnt anything special. That said, he is a unfinished product, he has alot of work to do, but there is no doubt he has alot of potential. For me, he isnt as much a potential starter for Real Madrid as he is the future hope of Norway, thats what matters most for me. We have been really starved of having a real international talent for quite some time now, hope Martin can change that.
