MOSCOW — Former Russia international Valery Karpin will begin his second coaching spell at Spartak Moscow after being named the club's caretaker boss Monday. “Karpin has been appointed Spartak's caretaker coach until the end of the 2012-13 season,” the club's spokesman Alexei Matveyev told Reuters. Karpin, 43, replaces Spaniard Unai Emery, who was sacked following a 5-1 home thrashing by city rival Dynamo in a Russian Premier League derby Sunday. He faces a stern test in his first game back Friday against champion Zenit St. Petersburg. Karpin has played with Spartak, Valencia, Real Sociedad and Celta Vigo. — Reuters
