FORMER Celtic striker Chris Sutton has launched a blistering tirade on his old club's decision to fly Christopher Jullien to their winter training camp in Dubai.

The French defender is out injured for the next three or four months and would have been unable to train, yet still accompanied the squad in the UAE.

Jullien tested positive for coronavirus on Saturday following a round of testing upon the players' return to Glasgow.

Thirteen first-team players, as well as manager Neil Lennon and assistant John Kennedy, have entered self-isolation as a result, wreaking havoc on the Parkhead club's plans.

In a video posted on Twitter, Sutton tore into the Premiership champions - arguing that Jullien shouldn't have even been in Dubai, describing his old side as a 'shambles from top to bottom'.

He said: "What an absolute mess Celtic are in from top to bottom. And the current statement regarding Christopher Jullien and contracting Covid was an utter embarrassment.

"The club need to take ownership on this one and they haven’t done.

"Talking of Dubai and being for performance reasons – well, Christopher Jullien, we’re told, is out long term.

"He’s out for months. The only place he’ll be performing in Dubai is on the treatment table or down by the swimming pool.

"Whether you agree with the trip to Dubai or not, Christopher Jullien shouldn’t have been there – absolutely shouldn’t have been there.

"And then the club are saying in their statement that this could have occurred in Scotland. Well, OK, that’s fine saying that but the fact of the matter is it may have occurred in Dubai with a player who shouldn’t have been there.

"This whole sorry mess sums up Celtic’s season: it’s a shambles from top to bottom.

"Peter Lawwell and Neil Lennon have to take responsibility on this one. The club have to take ownership and they haven’t done.

"They need to sort it out and sort it out now."
