Memphis Depay is desperate to score.

He has his fifth shot and none are on target. To be fair this one is deflected wide.

The resulting corner is played short by Daley Blind, Juan Mata flicks it towards the back post and a diving Anthony Martial heads wide.

He should score...

"Louis van Gaal's side have not had a single anxious moment and once Chris Smalling opened the scoring the contest looked over - and it surely is after Juan Mata's second."

I get the feeling this will be five in 45 minutes time...

Good defending from Junior Brown, who crowds out Anthony Martial as the Manchester United striker is about to shoot.

United start as they finished the second half. All over Shrewsbury.

Corner United but cleared.

Scott Williams: Northampton Town. The Big Easy.

Marc Platman: Leeds United this season - The Good the Bad and the Ugly

Gary Wroe: Man City and Gone with the Wind.

Shrewsbury's players are out very early and are performing their own version of the hokey-cokey.

Perhaps manager Micky Mellon was so angry at that first-half showing, he sent them out?

United are out now and away we go.

Rich Olyott: Shock as attacking play results in goal.

Soorya Thavaraj: Come on Shrewsbury! No one loses to #MUFC by two goals. They haven't scored two 1st half goals in ages.

This average position graphic pretty much sums that first half up...

Jean-Louis Akpa- Akpro is Shrewsbury's only player to have an average position inside United's half - and that is by a very small margin.

The vote is now closed.

So 27% of you think Chelsea will win the FA Cup, just ahead of Arsenal on 24%.

Eight per cent of you plumped for Shrewsbury...

"He just dinked it over the wall and in the corner. It's 2-0 and no more than they deserve. It's as easy as you like."

A blatant yellow card for Zak Whitbread as he trips Anthony Martial right on the edge of the penalty area.

Free kick and another golden chance.

He'll score this

Finally.

A couple of thunderous challenges from a couple of Shrewsbury players in the middle of the park.

They lose the ball but at least it looks like it matters at last.

Now, now, Gary...

Apologies for the lack of Shrewsbury players on the above goal graphic although it's not too unrealistic the way the Shrews are going about this...

United fans sing about Wembley.
