Wigan Athletic finally caved in, accepting a bid from Chelsea for their talented forward Victor Moses.

In a transfer saga that has continued all summer, Roberto Di Matteo ultimately got his man, with Wigan confirming they had accepted an offer, believed to be around £9 million ($14.2 million), from the Blues on their official website.

"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," a statement said.

"The player has been given permission to speak with Chelsea."

Personal terms should not be a problem, with wages reportedly already agreed between the player and Chelsea, so an official confirmation of the deal can be expected as soon as Moses arrives in London and completes a medical.

Moses becomes yet another youngster to join the Chelsea ranks at Stamford Bridge, with the likes of Eden Hazard, Oscar and Marko Marin signing earlier in the summer.

The deal seemed to have been clinched after Di Matteo insisted on putting in another bid, the one that was finally accepted, after Moses impressed for Wigan against the Blues in their opening match of the English Premier League season.

While Moses is not expected to immediately compete for a starting place, owing to the embarrassment of attacking talent now available to the Chelsea manager at Stamford Bridge, the 21-year-old will be useful as an impact sub.

Wigan manager Roberto Martinez will be disappointed to lose out on the Nigerian international, whose form was largely responsible for the Latics staying up last season. Martinez, had earlier in the day said there was no progress on the Moses-to-Chelsea move, but admitted he was the "wrong man" to ask anyways.

Martinez, however, revealed there was a price for every player, while abundantly praising Moses. "You will get all sorts of speculation and talk, but the reality is every player has a valuation," the Spaniard said. "If a club matches that valuation, then maybe you have to sit down with the player and there is a decision to be made.

"Victor is an incredible young man and I think the maturity he showed on Sunday (against Chelsea) is not normal in a 21-year-old.

"It has been a real joy to see him grow over the last few seasons. We made a massive investment in him as a young man and we are very proud of him."
