That's true on Mane, don't think Salah inclusion was down to us being too desperate. We had Coutinho who could play left and Mane doing the job on the right. Just that when entrusted with that position, Salah showed he can adapt quickly. That's how I see it...Fair point, although goalkeepers don’t count.
On the hand, the needs were far more desperate when each of Mane and Salah arrived.
