Zenit St Petersburg have sacked coach Luciano Spalletti a week before their Champions League last-16 second leg against Borussia Dortmund.
Spalletti, 55, departs on the back of a disappointing 0-0 draw at home to lowly Tomsk on Saturday, which allowed Lokomotiv Moscow to move two points clear at the top of the table. Zenit also suffered a 4-2 defeat in the home leg of their European tie against Dortmund, giving themselves an uphill task for next Wednesday's return encounter in Germany against last season's beaten finalists.
"Zenit's club management has decided to dismiss Luciano Spalletti from his duties as head coach of the Blue-White-Sky Blues," a statement on the club's official website read.
"Sergey Semak has been appointed Zenit's acting head coach."
Former Roma boss Spalletti took up the Zenit reins in December 2009 and led the side to two league titles, one Russian Cup and a Russian Super Cup crown.
He was also the first man ever to lead the club into the knockout phase of the Champions League, and was named coach of the year in Russia in 2010 and 2012.
The statement added: "We wish to thank Luciano Spalletti for all that he's done for the development of St Petersburg football, and we will always be happy to see him in St Petersburg! Grazie, Mister!"
