Leeds were absolutely rancid that first half against Arsenal and their captain is now suspended for the rest of the season. There is nothing suggesting to me that they'll be able to beat a motivated Chelsea side who need to make sure of Champions League.
If Chelsea perform to a similar level as they did against us, then Leeds could get a result. There will be a massive atmosphere there tomorrow and the first goal will be huge. If Chelsea get it, then I don't see much hope for Leeds. But if Leeds go ahead, then of course they could win. You can't rule out anyone at this stage of the season, especially not at home.
