I dont think his issue was injuries. It didn't help with us, but he played many seasons out on loan fully healthy without ever being good enough for relegation level teams.
He is the complete opposite of excellent or stand out, except for that euros 2016 sub cameo, we took a gamble and were burned hard, like many before who sign players who look nice in NT tournaments instead of properly scout them. Fools gold settings.
Honestly he is a big candidate for one of our worst signings in general, because he has been with us for 8 years, 2 of them prolonged due plusvalenza scheme, and truly, can you think of a Juve player more useless to the organisation at that time with that longevity?
He is so pointless past decade I am ashamed of myself for writing 3 paragraphs about him.
