Allan McIntyre has Tweeted me to predict an away win for Michael Laudrup's side. This is what he says: 3-0 Swansea to get them in the mood for their Europa League fixtures.
Big game for Scott Sinclair today, who starts against his former club, and the team, really, where he made his name. Anyone brave enough to back him to score against his former employers?
Another West Brom supporter Peter Willetts also feels Albion will claim a 3-1 win. He says: A must win for West Brom - otherwise confidence will go and the team will struggle. A tough match but I fancy a 3-1 Baggies win. Anelka to be amongst the goals hopefully.
West Brom fan Ken Pratt has got in touch with us on email and he says: This won't be easy but hopefully the Baggies will not only score their first premiership goal(s) of the season but also register our first win. I'll take Anelka, Morrison and Long to grab a goal each in a 3-1 win.
