QPR striker Charlie Austin has taken a swipe at Manchester United fullback Aaron Wan-Bissaka.

Austin scored in Saturday's friendly win against United.

Austin told talkSPORT: "Although Manchester United have signed [Raphael] Varane, their biggest problem is they need a right-back.

"Aaron Wan-Bissaka is not up to the [required] quality. We played them the other day, and I know it was only a pre-season, but they need to go all out for Kieran Trippier.

"That's who they're crying out for. Aaron Wan-Bissaka can't defend.

"And his final ball is not what a centre-forward wants, it's not what [Edinson] Cavani wants, it's not what [Marcus] Rashford wants. They need to sign Kieran Trippier."
