Chris Sutton pinpoints the Celtic upgrade that Ange Postecoglou must address ahead of Champions League surge

Chris Sutton insists Celtic still have an issue to address at left-back - despite the impressive recent form of Greg Taylor.

Taylor has made the position his own this season under Ange Postecoglou, and eventually became one of the first names on the team-sheet as the Hoops claimed a Premiership and Premier Sports Cup double.

But Sutton reckons his former club still need to invest in defensive reinforcements during the close season and singled out Taylor as one player who could still be considered an 'issue'.

Speaking on the latest edition of the Record Celtic Podcast, Sutton explained: "I still think left-back is a massive area for Celtic and they've had a weakness there for a number of seasons really.

"He's [Taylor] improving, and you might think I'm being harsh on him, but I'm just saying Celtic are now going into the Champions League.

"I'm here to be proved wrong but what worries me is against really top level opponents, can Greg Taylor cut it?

"This isn't me slamming him, although it sounds like it is, but you've asked me which areas of the team need improving and I think left-back is an area of concern.

"If I'm being honest, I think Juranovic is at the level the others need to aspire to.

"It's how you you view it. I'm talking about the top level. I'm talking about the highest, highest level."
