Norwich City defender Marc Tierney says Manchester United do have weaknesses that can be exploited.

Despite United's lofty current position right now, recent events have suddenly taken away a fear factor.

After defeat on Saturday, Tierney said: "Looking at the game against Basel, there were chances there.

"We saw a little chink in the armour and went for it.

"Whenever you see a team conceding three at home, it gives you that bit of confidence.

"Some people come here and are overawed by the stadium and beaten before they have set foot on the pitch.

"But that didn't happen to us. We made our mark on the game and had a go at it."
