CHRIS SUTTON has challenge Paul Lambert over his concerns about Celtic.

The Hoops were thumped 4-0 at home to Bayer Leverkusen in the Europa League last night, leaving them bottom of Group G.

The result means the Hoops only have two wins in their last five games.

Speaking in the aftermath of the defeat, featuring on BT Sport for punditry duty with Neil Lennon, Lambert raised certain worries about his former club becoming a "nearly clubs".

He warned Ange Postecoglou he’s got to start winning SOON.

Lambo said: “Celtic’s not a developing club, it needs winning. If you play here you HAVE to win games.

“You can be nearly, nearly, nearly all you want - it doesn’t matter.

“If you don’t win here you’ll get criticised because of the size of the club.

“That’s the one thing that annoys me with it - ah, we’re unlucky, we’re unlucky.

“This club is built on WINNING.

“That goes back to the great Jock Stein era and the Lisbon Lions.

“For me the club is in danger of being on the peripheral.

"There has got to be a reaction up at Aberdeen on Sunday."

But while he understands what Lambert is saying, Sutton challenged the ex-Ipswich boss on his views - telling him to lay off Ange when he's so early into his tenure.

He tweeted: "It’s ok Paul Lambert saying Ange Postecoglou needs to win titles and the club is all about winning etc but he’s taken over a s***show and been in the door 3 months…"
