Juventus v Celtic preview: Johan Mjallby says Hoops must keep cool in Turin

The Hoops were left seething after their 3-0 first leg defeat at Parkhead, which saw the home side win 10 corners but fail to make anything of them, in part due to the Italians grappling off the ball.

Gary Hooper and Scott Brown were both booked in penalty-box clashes, as were Juventus duo Stephan Licht­steiner and Simone Padoin, and Celtic manager Neil Lennon asked Uefa for an explanation of the performance of Spanish referee Alberto Mallenco.

On several occasions Mallenco turned a blind eye to shirt tugging from the Juventus players and Lennon claimed afterwards that his team were denied at least one penalty.

Mjallby, whose side need a miracle to make the quarter-finals, said: “We watched the previous game they played, against Napoli away and I have to say they did the same thing again.

“They were marking their opponents very, very roughly and hard when it comes to corner-kicks and wide free-kicks against. We just have to be ready for it and hopefully the referee is very strong if it happens again.

“They should always be strong, that’s their job. If the referee thinks it’s a penalty and if it’s a penalty by the rule book then it should be awarded a penalty.

“If we give back the same medicine, you never know what is going to happen.

“We just need to be strong mentally and maybe move about a wee bit more and see if it’s harder for them to mark us.”

The Hoops will be without injured striker Tony Watt, as well as Scott Brown and Mikael Lustig. Charlie Mulgrew travelled after missing the last three matches with a muscle problem.

In tomorrow’s other last-16 clash, Paris-Saint Germain take a 2-1 lead into their tie against Valencia.
