Chelsea to win this match
I am sure that Swansea plan for reaching Wembley is to draw away and win home, not sure if they will be able to bring it to life. I do remember the match at Liberty stadium that happened a bit more than a month ago, I do remember the score line (1-1), however that was away game and Chelsea have improved a lot under Rafa. Also now they have that goal-hungry forward they needed so much. Ba in my opinion is perfectly suited to be that cutting tip of Chelsea attacking formation.
I do not deny that Swansea have quality to draw or win this fixture on their good day and Chelsea bad day, but I think that chances of this happening are very slim.
My bet is Chelsea to win.
