BORUSSIA DORTMUND V WOLFSBURG: HOSTS AIMING TO KEEP DIMINISHING TITLE HOPES ALIVE

A first-half humiliation was more than enough for Dortmund to secure a top four spot and put the pressure on Bayern Munich.

A great BVB performance in front of a capacity crowd however Wolfsburg were embarrassed and need to launch an inquest into that first 45 collapse.

Wolf and Rothe off. They are replaced by two teenagers in Semic and Bynoe-Gittens.

Arnold prides himself on his good delivery but that's a number of crosses that are easily headed out by Dortmund.

Wind is replaced by 20-year-old Bialek.

Something for the Wolfsburg fans to cheer and no clean sheet for BVB.

Sloppy control from Pongracic sets Nmecha through on goal, he can't find a way past Kobel but it falls to Baku who hits a powerful strike into the net.

Witself is taken off and Reinier comes on - he is in need of game time having rarely featured this season.

Dortmund have injury problems so their bench is full of young players - 6-0 is the perfect chance to give some of them an opportunity if Rose wants to.

Dortmund are just seeing the game out - they must now be thinking about next week's match versus Bayern.

Wolfsburg have improved a little but it is helped by Dortmund's now relaxed attitude.

It's the sub Vranckx who strikes a powerful shot off the top of the bar.

Arnold crosses in a free-kick and it's not dealt with and it falls to Vranckx on the edge of the box but they don't get a consolation goal.

Akanji is off and Pongracic is on.

Also, Brandt is subbed and another 17-year-old is on - it is the highly rated Moukoko.

The injured Schalger goes off for Vranckx and Lukas Nmecha is replaced by his brother Felix.

He's through again but this time he is denied by Casteels. That could've and should've been his hat-trick.

A break in play as the midfielder gets treatment. We see replays of that fantastic sixth goal - great one touch football.

Another goal and it's Haaland again. Reus puts it into the feet of Brandt who instinctively pokes a ball behind the defence to Haaland who smashes in from a tight angle. Great team play.

Dortmund are playing with confidence. Brandt is showing his technical skills with flicks and tricks and they're all coming off.

Reus is one on one with the keeper but Casteels makes a good save but the attacker perhaps tries to be too clever with the finish.

There was a change at half-time for Wolfsburg as Kruse goes off for Roussillon.

Wind hits it and it is saved well by Kobel. Wolfsburg then get a number of corners but they are all dealt with - this is a better start.

Will the humiliation continue in the second half?

A simply incredible 45 minutes comes to an end.

Everything Dortmund touch turns to a goal but Wolfsburg need to take a long hard look at themselves. The defending hasn't been good enough and Casteels in goal will not be happy with himself - some of those strikes should be saved.
