Semak injury adds to Zenit worries

ST PETERSBURG, March 7 (Reuters) - Zenit St Petersburg midfielder Sergei Semak will miss at least a month with a foot injury, adding to worries for the Russian champions just days before the start of the domestic league season.

Zenit said on their website that Semak would be out for four to six weeks after breaking his foot in a 2-1 win over CSKA Moscow in the Russian Supercup on Sunday.

"It's going to be very tough for us with so many injuries," Italian coach Luciano Spalletti, who last year led Zenit to a domestic league and cup double in his first season in St Petersburg, told reporters after Sunday's victory.

Winger Vladimir Bystrov will also be sidelined for at least six months after undergoing surgery to repair ligaments in his knee last week, while leading strikers Alexander Kerzhakov and Danko Lazovic are struggling to be fit for Sunday's league opener against Terek Grozny.

Zenit, who face Dutch side Twente Enschede in the Europa League last 16 later this month, said they wanted to sign a "top player" before the Russian transfer window closes on Friday.

Media reports said the big-spending club, backed by Russian energy giant Gazprom, have been pursuing Spartak Moscow's Irish international midfielder Aiden McGeady among others.
