if you're trying to challenge an argument that says rarely, I'd advise to use more than 1 example

Arsenal over the last 2 decades have bought heaps of talent, but hardly anyone has enjoyed a successful career, especially after leaving Arsenal. Fabregas had 1 good season outside of Arsenal, Nasri none, Gervinho ended up in China and half of them I don't even remember. At the end of 90ties and start of 00ties it was better of course, but they've been crazy unsuccessful in developing players for more than a decade now
