Depends what time the do finishes I guess. Cheers for the Curzon St tip, v helpful 
No worries. Just looked and the area I'm thinking of is Shepherd market, just off Curzon St. Only ever been there at lunchtime and the boozers were a bit old mannish so can't guarentee they would have the game on but I think they would be the closest you'll find.
Edit - Ye Grapes
16 Shepherd Market, W1J 7QQ
Ye Grapes is a handsome old building set in a corner of Shepherd Market, containing an eccentric collection of olde worlde knickknacks creating a cosy sort of feel to the interior. It's been a favourite of the people who work and live around here for a good while now, but, until recently it seemed to have been experiencing something of a decline. Now that negative trend appears to have been reversed. The interior has been repainted and the seats reupholstered, the plentiful staff are attentive and, most importantly, there's decent ale all on all six hand pumps, pretty much all of the time. (Previously, there had been times where there was no beer at all.) The beer is pretty good with a few interesting guests mixed with predictable regulars such as Pride and Doom Bar. For the hungry, there's Thai food available seven days a week and there are a couple of TVs for the sport. We're happy to report the Ye Grapes is pretty much back to how it used to be: a popular, loquacious, vibrant pub - it's what the market needs.
