Not sure if I should continue that joke as it can turn very dark (I have severe but stable health issues
).
Martin Ødegaard to my knowledge hasn't had any chronic issues, but I did some searching and a
fairly new article (this year) wrote about him having
patellar tendinopathy, which again google says basically gives you pain in the knee and occasional swelling. Guesswork from myself, someone who obviously don't know anything about this makes me think he'll be able to play perfectly fine but could need to be managed more, so won't play all games like most healthy players at his age would.
Even so, he
has been playing through the pain for Real Sociedad, so it goes to show that unless it gets a lot worse he should still be able to have a good career. And if not, he should be damn happy he chose the money in Madrid before development in another country with the new predicament.
Something that should worry others who now would consider him for United is that if this issue is recent, he has had a big fall in productivity after the first half year, so it could be that the pain is hindering him when he is on the field. I haven't watched the games though, but that is how his progress has been reported in Norwegian media during the season: Great start but fading as the season has gone from midway to a close.
