51mins: Should have been a second for Latics! Great delivery from the left side onto the head of McArthur, but it goes agonisingly wide. The stadium is rocking right now!
50' Great start to the second half for Latics, the ball comes in near post down the right for Powell and he bundles the ball in.
49' Crainey wins a corner down the left wing after a solid run, Latics pressing Derby now! McManaman header from the corner goes across the area.
48mins: CHANCE! Crainey delivers a free kick from the left wing, Boyce rises to connect, but Grant holds his position in the centre of his goal and catches.
47mins: Frustration already as Will Hughes twists and turns on the ball just inside Latics' half and Powell commits a foul.
Double change at half time for Latics, Grant Holt and Roger Espinoza replace Will Keane and Ben Watson. #wafc
The players are back out on the pitch for the second half.
I'll be back shortly for the second half. Thanks for following the updates on here, also nice to see all of your considered opinions.
45+3mins: YELLOW! James McClean in the book for a wild sliding challenge. His frustration was clear to see and that booking was coming for a while.
Great effort from the full back, but nobody was there to follow it in.
45' OFF THE BAR! Stephen Crainey loops it over the wall and it bounces back down off the woodwork.
44mins: McClean dribbles through three defenders and is eventually pinballed to the ground by Hughes and Keogh on the edge of the area. Free kick to Latics, Watson, Ramis and Crainey over it.
42mins: Frustration kicking in everywhere today. Ivan Ramis has given away a few cheap free kicks, but he's remained calm at the back.
39' Just have to keep plugging away Tana. James McArthur shows his graft as he wins the ball in the Derby half and runs at the defence. He skips beyond two challenges in the area and tries to play it back into the area, but the keeper Grant makes a good interception.
37mins: I've got to be fair to Derby here and say they've done their job. They've pushed and harried out defence and it's caused us the problems that the score line suggests.
