The Baggies midfielder believes his side were unlucky not to take a point from Stamford Bridge on Sunday.
West Bromwich Albion midfielder Darren Fletcher was left frustrated with his side's 1-0 Premier League defeat to Chelsea at Stamford Bridge on Sunday, after what he described as a near-perfect game plan.

Heading into the trip to West London, Tony Pulis' men were unbeaten in four league games, having dropped just two points out of their last 12.
A West Brom side that have taken a point from Stamford Bridge in two of their last three visits dug in manfully, but with less than 20 minutes to play, a rare error from Gareth McAuley saw the red-hot Diego Costa steal in for the decisive goal of the game.
Fletcher rued a missed opportunity to take what would have been a hard-earned point - against the side now favourite to lift the league crown on current form - adding the lack of chances West Brom created themselves led to their own downfall.

Fletcher told wba.co.uk: "I thought we played really well today in terms of what we tried to do. The game plan worked perfectly and we were a bit unlucky to lose the game"
"Chelsea didn't really create any chances and we've had a few little half opportunities here and there. We'd have liked to have done better with the ball but it's difficult at times."
Since making the switch to The Hawthorns on a free transfer in February 2015, the Scottish international who had spent 12 years at Manchester United has revived his career after a troublesome spell with illness and injury.
Now 32, Darren Fletcher's tireless work-rate has ticked a big box for his manager Tony Pulis, with Claudio Yacob as the perfect foil in The Baggies usual five-man midfield.
The Scot have been a vital cog in a West Brom unit that have surprised many with an attacking verve to their game, as well as Pulis' customary defensive discipline that have lifted the club into the top half.

Attentions now focus to the first of six games over a busy festive period for the Baggies and Fletcher believes his side can take positives from the loss.
"It's another continuation of the good performances", said Fletcher. "[You know] you come to Chelsea, you're really disappointed to have lost one nil and you feel like you could have taken at least a point from the game."
"It shows were heading in the right direction. The consistency's been good, it's an unforgiving league and there's gonna be games like this. This is the Premier League it's tough."
