Scholes told The Overlap, via Sky Bet: "I've heard a lot of United fans saying they're excited for the new season, but I'm struggling to get excited. The middle of the pitch being an area where we're just f*cking empty. Teams just breaking through us."
He added: "I still worry about the goalkeeper, he's a big concern for me. Even watching the pre-season games, a couple of goals he conceded against Liverpool... I worry to death about him."
