I'll never get the caf's obsession of downplaying one of our players' achievements. Literally every player goes through a rough patch, young players more so. Rasher's recent performances are worthy of criticism and they should be but it is beyond stupid to call him overrated and all.
Rooney and Ronaldo both had rough patches. They aren't highlighted due to the team strength. They started off with RVN, arguably our greatest finisher ever, as their strike partner and later had Saha and Tevez as well. Add to that, we had Scholes, Giggs, Ji, and some great fullbacks as well providing chances after chances and goals after goals.
If you want to compare his performances then compare them against 21 year old versions of various strikers, even then he'd be in the top bracket, or just slightly lower
