BERLIN — Former Chelsea and Tottenham Hotspur coach Andre Villas-Boas will take over Russian side Zenit St Petersburg this week after agreeing on a two-season contract, the club said Tuesday. Villas-Boas takes over after Zenit sacked coach Luciano Spalletti earlier this month and appointed caretaker Sergey Semak, who will be in charge Wednesday in their Champions League return leg at Borussia Dortmund for a spot in the quarterfinals. “Zenit has agreed terms on a contract with new head coach Andre Villas-Boas,” the club said in a brief statement. “The contract will be signed and Mr. Villas-Boas will be presented in St Petersburg as Zenit's new head coach on March 20.” — Reuters
