Ending days of speculations on signing Victor Moses of Nigeria, Chelsea FC has finally completed transfer deal with Wigan Athletics, agreeing for a £9million fee.

The signing of the transfer deal came just hours after Wigan manager Roberto Martinez called Chelsea "cheap", stating that top clubs just take players they want.

"The club can confirm that after four unsuccessful bids from Chelsea for Victor Moses, a fifth bid has today finally met the valuation and terms set by Wigan Athletic and been accepted. The player has been given permission to speak with Chelsea," the club gave out a statement on Thursday.

Chelsea manager Roberto di Matteo had earlier praised Nigeria winger Victor Moses following his good performance against Chelsea in the opening weekend.

Moses, who joined Wigan from Crystal Palace in 2010 on a three-and-a-half-year deal, has contributed big to the club, scoring eight goals in two seasons.

Chelsea FC tops the Premier League table, starting the season in style with two consecutive wins. Fernando Torres' controversial goal put the Blues ahead of Reading on Wednesday's match, which they won 4-2. They had earlier defeated Wigan Athletics 2-0 in the opening game last weekend.

The European Champions have already signed big players like Germany's winger Marko Marin, Belgium's forward Eden Hazard and Brazil's playmaker Oscar Dos Santos to fulfill club owner Russian billionaire Roman Abramovich's dream of transforming the club into an entertaining one.

Chelsea had spent around £46 million in 2011 by signing Romelu Lukaku, Romeu, Juan Mata and Raul Meireles.
