MANCHESTER City boss Roberto Mancini has flexed his muscles in an internal battle about player recruitment.

The fiery Italian has never been afraid to vent his frustrations at what he views as unnecessary delays in bringing in new players, with him now letting rip towards Brian Marwood.

The football administrator has remained in Manchester while City have embarked on their short Far East tour, and Mancini is not happy with the work being done to strengthen his squad.

"It is important [to get players quickly] because, after what we did last year, we must continue to win," said Mancini ahead of tonight's friendly with Arsenal in Beijing.

"This year will be harder than last so we need to improve our team. We have a man who works for this and we hope he can do a good job."

The good news for City is that skipper Vincent Kompany has committed his future to the club by signing a six-year deal which will net him £30million if estimates of a £200,000 weekly salary are accurate.

As Kompany remains in England, ex-national team boss Fabio Capello has set his sights on taking Russia to the World Cup in 2014.

The Italian signed a two-year deal yesterday to succeed former Ibrox boss Dick Advocaat, who revealed his intention to step down and take over of PSV Eindhoven before Euro 2012.

"The current contract runs for two years," said Capello. "And my next goal – to reach the finals of the World Cup.

"After I had finished working in England, I was angry, and I wanted to continue working.

"I really want to achieve your goals and fight for the Cup in Brazil.

I want to give players the will to win, the desire to always fight for victory."
