"It has been a fairly scrappy second half so far, which will probably suit Barnsley, who have had a bit more of the ball.

"The Tykes have carved out the odd chance and look more inventive from set-pieces.

"Millwall have been going more direct and the link-up play between forwards Lee Gregory and Steve Morison hasn't been as good since the break."

After such a high-tempo first half, perhaps it is no surprise that things have slowed down since the break.

Plus, Barnsley are obviously keen to keep things tight. Millwall need to find a way of changing things. They have less than 25 minutes left.
