They look like they're going to keep their three at the back.

We have to just keep our foot on the gas, we have to keep doing what we're doing.

The boys have really got their act together in this half.

Middlesbrough keep pressing forward.

Matt Targett's cross finds Alan Browne whose header is comfortably saved by Radek Vitek.

Almost 2-0 to the hosts.

Will Lankshear gets through and plays a lovely chip over Addicks keeper Will Mannion.

Mannion just gets enough on it to slow it down and give Lloyd Jones enough time to get there and clear the ball off the line.

Good goalkeeping there from Mannion.

Moments after spurning that big chance, Haji Wright is replaced by fellow striker Ellis Simms.

At the other end, Haji Wright should make it 1-1!

Milan Van Ewijk stands up the perfect cross for Wright to leap and attack.

However, his header is straight down the throat of Southampton keeper Daniel Peretz.

Big opportunity wasted.

First changes of the game as Kim Hellberg looks to his bench as his side look to find a breakthrough.

David Strelec is on for Riley McGree and Jeremy Sarmiento makes way for Leo Castledine.

Another yellow card for Bristol City as Sinclair Armstrong is their fifth to go into the ref's book for a late challenge.

Looking at the penalty again and I'm not sure what Kayne Ramsay is thinking there.

The ball is swung into the box and is going harmlessly into the arms of Will Mannion, but Ramsay just shoves Will Lankshear in the back needlessly.

The Oxford striker isn't getting anywhere near that ball.

Nathan Jones is going to react by taking Ramsay off and bringing on another striker in Charlie Kelman.

The Addicks will need to open up now, they've been very inaffective up front so far.

Chance for Saints to double their advantage.

Casper Jander is slipped in but his effort is straight at Carl Rushworth.

Jander probably should have made more of it than he did.

Matt Grimes whips in a free-kick from the left but Daniel Peretz comfortably gathers before going down under an aerial challenge from Liam Kitching.

Free-kick to Southampton.

That should be a goal, but he's stopped that right on the line.

Credit to Vitek, he's done what he can. It's a big outstretched foot and outstretched hand to stop it on the line.

That was a mad five minutes, City have done well to come through unscathed there.

Boro were asking the questions but City had all the answers.

Radek Vitek keeps Middlesbrough out with a corking triple save.

First he keeps out Aidan Morris' strike from 20-yards which he's unable to keep hold of. He then makes an incredible stop with his legs to keep out Alan Browne's rebound and then keeps hold of the ball on the line to stop it trickling over.

Tremendous goalkeeping.

A great cross from the left side by Coventry's Jay Dasilva finds Liam Kitching but he heads his effort wide.

Josh Eccles is then immediately replaced by Sky Blues boss Frank Lampard for Brandon Thomas-Asante in an attacking change.

Big chance here for the hosts.

Kayne Ramsay bundles Will Lankshear over in the box and Cameron Brannagan has the opportunity to give his side the lead from the spot.

Charlton's first chance of the game and of course it comes from a Harry Clarke long throw and Conor Coventry heads wide.

Ryan Manning whips his effort over the wall but it drifts just wide of Carl Rushwoth's left-hand post.

Chance for Oxford as Michal Helik gets on the end of Sonny Carey's header back that was meant for his keeper.

Helik gets there first and looks to dink it over Will Mannion, who clatters into the Oxford defender with the ball lobbing over the Addicks goalie and over the bar.

Oxford call for a penalty but it's very muted and nothing doing for the referee.

A double booking for Bristol City as Sam Morsy and Scott Twine both go into the referee's book.

Twine is booked for a late challenge and Morsy for dissent.

How will Coventry respond now?

Well, they've not started too well, and defender Liam Kitching is booked for a pull back on Cyle Larin.

Free-kick potential for Ryan Manning here.
