Former Sunderland and Leeds manager Peter Reid has told the Daily Record that Celtic manager Ronny Deila must focus on improving his defence this summer.
Reid, 59, is currently managing in India with Mumbai City, but will be best known for his spells in English football with Manchester City, Sunderland, Leeds United, Coventry City and Plymouth Agyle.
The Daily Record claim that the Liverpudlian is actually a Celtic fan, and the former Thailand boss has been speaking about his favourite club.
The Bhoys face Icelandic side Stjarnan in the Champions League qualifiers this summer, with manager Ronny Deila hoping to do what he couldn't a year ago - reach the group stage.
Summer signings will be needed, and whilst Manchester City defender Dedryck Boyata has already arrived, Reid has given Deila some advice, recommending that he should look to bring in more defensive help - though keeping hold of in demand defender Virgil van Dijk would be great news.
"I’m sure there will be a few additions in the weeks ahead but there’s enough quality on board to navigate through these qualifiers," said Reid. "The defence probably needs strengthened but if Virgil van Dijk remains at the club then it will be a huge boost."
"A couple of tweaks is all that may be required as there is a consistency of selection now and Deila doesn’t have the disruption of being just in the door as he was this time last season," he added.
Where should Deila strengthen?
If Deila chooses to focus on defence - a unit which conceded just 17 goals in the Scottish Premiership last season - then a couple of areas could be vital.
Boyata may have arrived, but he joins as a replacement for loan star Jason Denayer, who has returned to Manchester City after a superb loan spell with the Bhoys.
Another centre back could be added even before any decision is made over the future of star centre back Virgil van Dijk, who is likely to attract interest from Premier League clubs.
The second area would be left back, given that Emilio Izaguirre has little competition for his role in the first team. Bringing in someone to compete with the Hounduran would be a wise move from Deila, who will be looking for a strong squad to challenge in multiple competitions next season.
