Robben was injury prone before he hit 30. Ribery had injury issues before he hit 30 as well. In any case, they didn't drop off the face of the earth when they did turn 30.
There are plenty of other attacking players who continued to play well, if they avoided injuries, into their 30s.
But the way people talk about our front 3, is as if they're already in their 30s and are past their best.
Never ever have I ever seen this discussion take place any time before about any club, except for us, including our own supporters. It's weird really.
