Soccer-Advocaat backs volatile M'Vila to make big impact at Sunderland

Aug 12 (Reuters) - Sunderland manager Dick Advocaat is confident new loan signing Yann M'Vila can put his controversial introduction to English football behind him and "make a big difference" to the team. The temperamental French midfielder was sent off for headbutting Norwich Under-21 forward Jamar Loza during his club debut on Sunday. "He is a quick thinker. He will make a big difference to the team," Advocaat told the Chronicle. "He is a controlling player rather than box to box," the 67-year-old former Netherlands manager said, impressed with M'Vila's skills. "He is more a passer of the ball, picks a great pass and a quick pass. (He) does well with that." Sunderland, who lost their opening league game 4-2 at the hands of Leicester City, host Premier League new boys Norwich City at the Stadium of Light on Saturday.
