Coutinho's best spell as a professional footballer came when he was trying to get Liverpool back into the Top 4. Willian, as much as we shit on him, will give Arsenal much needed experience and depth.
Like I said, we are laughing now, but I will genuinely be concerned if Arsenal line up like this next season.
