That's why you put a man on the post... Mark Durnan flashes a header on target from a United corner but Nick Ross is in the right place to boot it clear.

Better from Dundee as a Gary Harkins header is deflected narrowly wide and United are scrambling to clear from the following corner.

Dundee manager Paul Hartley cuts a frustrated figure on the touchline as he sees his team pump a series of aimless, long balls forward. The home side need to get Greg Stewart involved again. He was the man making things happen in the first half.

The visitors make a change as Scott Fraser is replaced by Ryan Dow in midfield.

Can United build on that Edward Ofere goal? They certainly have the upper hand now as Dundee struggle to find any kind of response.

The visitors have been given a huge lift by that goal and suddenly they are winning all the loose balls and breaking forward with menace looking for a second.

Now Dundee are shouting for a penalty as Edward Ofere barges into the back of Darren O'Dea. It was clumsy. Very clumsy. But, again, Willie Collum waves play on.

Now Simon Murray is penalised for tangling with Julen Etxabeguren on the edge of the Dundee box. The United forward is feeling very hard done by at the moment.

Simon Murray goes down in a heap under a challenge from Kosta Gadzhalov, who may just have stood on the United forward's toes, but referee Willie Collum is not interested.

We're off again. Can United find the win they need to avoid the drop? No changes in personnel.

Blue Monday on now. The stadium announcer is on fire!

Daydream Believer blasts out at Dens Park, with the "cheer up sleepy Jean" lyric perhaps taunting the visiting fans... The away end is not full, which speaks volumes for the mood at Tannadice.

"I just cannot see where United are going to get a goal from," says BBC Sportsound's Tom English. "Nothing is happening for them and Dundee look very comfortable. Whenever there is a 50-50, Dundee are winning it."

Dundee have been in charge without making their superior play count. United need to find a way into this game or they are going down - at the home of their fiercest rivals.

Craig Wighton shows good determination to get a shot off at the edge of the United box but the strike lacks power and it's easily scooped up by keeper Eiji Kawashima.

Dundee United defender Mark Durnan steals a yard on a near post run to meet Blair Spittal's corner but gets too much on his header and can't glance it on target.

Best chance of the game so far... Dundee sweep forward and Nick Ross slips the final pass into the path of an unmarked Kane Hemmings at the edge of the penalty box. He'll need to wait for goal number 26 of the season though as he leans back and sends a shot over the top.

United are exposed by a high, dipping cross from Dundee full-back Paul McGinn. Kane Hemmings has to stretch to get a boot to the ball and can only awkwardly divert it away from goal from inside the six yard box.

Dundee continue to boss the ball but they maybe need a bit more composure in the final third. Neither goalkeeper has been called into action.
