That's great. This would make Schalke 04 have him even more. 

It's just my thought - Eredivisie and Bundesliga levels are different. And 37 year old is moving to a better league so it sounds like Schalke are playing a bit of gamble to me. There have been many players who have struggled adjusting into better leagues plus Bundesliga is not similar as it was when he was at Schalke. Lot of things have changed.

Although I think it still will be a good deal considering he wouldn't cost much considering his age and contract he has left but still even if they do sign him it would be better if they find another attacking option in this transfer window to play  alongside Huntelaar.
