A superb display from Middlesbrough.

Christian Stuani gets one last effort in on goal for Middlesbrough from distance and David Stockdale is down to his right to save it.

Three minutes added on at the end of the 90.

The punishment is almost over for Brighton....

More joy on the faces of the travelling supporters, including a guy dressed as a donkey.

No sign of Joseph and Mary though...

Into the last minute.

Some despondent looking faces in the crowd among the Brighton fans. Made all the more exaggerated by them wearing seasonal outfits.

They've been given a bit of a lesson here today by Middlesbrough.

The Boro fans, meanwhile, have an enjoyable 315-mile trip home.

Jose Mourinho will no doubt be thrilled for his old friend Aitor Karanka in this one.

The Special One's seen enough and is off out the ground to beat the queues on the A27.

Last change for Boro as Adam Clayton gets a rousing round of applause from the visiting supporters and Manchester City loanee Bruno Zuculini comes on.

More tributes and memories can be found here.

More than 26,000 at the Amex watching this one according to the attendance just announced.

The majority are going to see Brighton lose a league game for the first time this season.

Around about 1,300 have made the long trip down from Teeside for an early Christmas present.

Albert Adomah fells Rajiv van La Parra on the right as Brighton look for some magic.

Free-kick is poor though and once more Boro can deal with the threat.

Half sight of goal for Bobby Zamora as he meets a cross from the right.

But, his header has little power on goal and Middlesbrough clear with ease.

Double change for Brighton as midfielder Andrew Crofts comes on for Jamie Murphy and Tomer Hemed makes way for Bobby Zamora.

Middlesbrough switch Emilio Nsue for Tomas Kalas.

Coming up to nine hours since Middlesbrough last conceded a goal.

Brighton still not looking like the team who will break that.

Jason's not wrong there. Boro have dominated this one, right from the kick-off.

The defensive record speaks for itself really. Aitor Karanka's side heading for a fifth win in six games.

They say silence is golden, but not in this case around the Amex where you can almost hear a pin drop now among the home fans.

A pocket of Boro fans pierce the silence as they are bouncing and heading to the Championship summit at Christmas.
