Wigan Athletic have rejected an undisclosed bid from Chelsea for forward Victor Moses, according to Sky Sports. A report in the Daily Mirror, a day earlier, quoted a possible price of £10mn.

The Nigerian international has only a year left on his contract with the Latics and though the club is keen to hold on to their star man, it is understood the player wants to leave the DW Stadium. Chelsea kept tabs on Moses all through last season and the former Crystal Palace man was watched on numerous occasions by Chelsea sporting director Michael Emenalo. Although the intial bid was rejected because it fell well short of Wigan's valuation of the 21 year old, the two clubs are expected to continue negotiations.

The Daily Mirror report also said Moses' arrival could lead to the departure of Daniel Sturridge, who is said to be unsettled at Stamford Bridge after falling out of favour under manager Roberto Di Matteo. Moses, who operates primarily as a winger, scored six league goals for Wigan last season. The player had a key role in Wigan's successful battle against relegation last term and has been linked with a move to a host of clubs this summer.

Meanwhile, Chelsea midfielder Juan Mata has confirmed he will represent Spain at this summer's Olympic Games.

The 24 year old, who has been unused so far at the ongoing 2012 European Championships, will miss a large part of the Blues' pre-season programme if he participates in the 2012 London Olympics' football tournament. Mata however insists he will compete for Spain and also that the west London club had given him their permission.

"My dream is to win in London. I have confirmed with Chelsea that I can play the Olympics. It's something I have agreed with the Spanish federation, and I don't want to change. My dream is to play and win the gold in London. After winning a lot with Chelsea last season, that would be another great honour," the Telegraph quoted Mata as saying.

Spain have been drawn in Group D, alongside Japan, Morocco and the Honduras.
