ZENIT St Petersburg were left stunned as Celtic laid siege to their goal during the first half of last night's Europa League last 32 meeting in Glasgow. 

Brendan Rodgers' side put in a superb performance at Parkhead to take a 1-0 lead into next week's second leg in Russia. 

And the visitors' official Twitter account commented at half-time that the club's two-month long winter break had left the team 'under siege', admitting that it was 'miraculously still goalless.'

The club wrote: "35 - Four good chances for the home side not taken, only the lack of finishing in front of goal stopping Celtic leading, Zenit surviving and need to tighten up.

"41 - Lunev's goal under siege and the boys at the back working overtime, miraculously still goalless.

"H/T - Celtic 0-0 Zenit. The Scots firmly in control but not able to find the breakthrough. No amount of friendlies can prepare you for a game of this intensity."

At full-time, the club posted: "Zenit not at the races after the long winter break."

Zenit manager Roberto Mancini also took to Twitter after the game, writing: "It was only the first match. Nothing is lost, we can recover!"

The Hoops travel to the Krestovsky Stadium next Thursday for the return leg as they look to book a place in the last 16, with kick-off set for 6pm UK time.
