Wolves boss Mick McCarthy still thinks that the Championship promotion race will go right down to the wire.Tuesday night's thrilling 3-3 home draw against Norwich City helped Wolves extend their lead to five points over Reading, who have a game in hand.But McCarthy told BBC WM: "It'll be a scrap to the bitter end."People turn up and we get wrapped up with beating Norwich and being clear at the top but you don't always get it the way you want."McCarthy's men twice led, 20-goal top scorer Sylvan Ebanks-Blake having netted the first of the night before completing his hat-trick to put Wolves ahead again at 3-2.But Wolves could not hold on to the win that would have taken them seven points clear, Gary Doherty cashing in a poor piece of defending from a corner to equalise. And the Wolves boss knows victory should have been theirs."They've got some good players and made it difficult for us but I'm really annoyed we couldn't see the game out," he said."It's not a foregone conclusion that we're going to win but we've really got to defend better."
