Will Zenit be able to last pace?

Courier Sport looks at three talking points ahead of the second leg of the last-32 clash.

How strong is Zenit’s staying power?

After going more than two months without a competitive game, Zenit were thrust into the cauldron of Parkhead and they struggled.

The Russian side looked off the pace and barely threatened the Hoops goal.

For a team which cost so much to assemble, it must have been dispiriting for few hundred supporters who followed them to Celtic Park.

To what extent that 90 minutes benefited Roberto Mancini’s team remains to be seen but it is unlikely they will outrun the Scottish champions, especially in the latter stages.

Will one goal be enough for Celtic?

Callum McGregor’s thrilling strike separates the sides and obviously the Hoops would have liked at least one more goal for the trip to Russia.

However, it is unlikely that the Scottish champions will try simply to defend that slender lead.

Boss Brendan Rodgers claimed after the first game at Parkhead that Zenit would have to come out more and that could play into Celtic’s hands.

Is the temperature rising?

They have a winter break in Russia for a reason and it promises to be a cold, cold night in St Petersburg.

The minus temperature during the game could go into double figures.

However, the good news for Celtic – and their fans – is that the stadium roof will be closed and conditions will be perfectly fine.
