THE main thing for Celtic to concentrate on before the game in Turin is their defence.

This week against Motherwell and St Mirren, the Hoops rearguard has looked susceptible.

With all due respect to the two SPL teams, but if they can find a way to trouble the SPL champions then Juventus will surely find a way through without too much trouble.

Thomas Rogne and Kelvin Wilson do not seem to have gelled as a partnership, while Efe Ambrose was all at sea in the first-leg against the Italians. Admittedly, he had walked off the plane from the Africa Nations' Cup final and into the dressing room.

It may be that Charlie Mulgrew returns to partner Wilson. There is also the added complication that Celtic are chasing a 3-0 deficit and go into the tie knowing it is over.

They need to be sensible, contained and simply try and ensure they come off the pitch without further damage to their credibility after such an impressive European campaign this season.

KEEP IT TIGHT says GRAEME MacPHERSON

NEIL LENNON is faced with something of a dilemma ahead of the second leg of their Champions League tie with Juventus. Three goals down from the first match, he knows that Celtic need to set up in positive fashion to try to claw back the deficit.

Too attack-minded, however, and it could allow Juventus to exploit them on the counter attack. The tie may be all but gone but Lennon won't want his players to be humiliated.

Celtic lined up in a 4-4-2 shape against St Mirren on Saturday but Lennon may consider a move to a 4-3-3 set-up that offers width in attack while retaining bodies in midfield. Georgios Samaras will likely be restored to the starting line-up wide on the left, with James Forrest on the right, both linking with central striker Gary Hooper.

The most attacking role in the three behind them may go to Kris Commons, with Joe Ledley, Victor Wanyama, Efe Ambrose and Beram Kayal battling it out for the two deeper midfield positions.
