Former Sunderland defender Gary Bennett on BBC Newcastle: "Question marks are going to be asked about Wahbi Khazri. If he can't get into this Sunderland team then he is looking at the exit door isn't he?"

Papy Djilobodji goes forward for a set-piece, but his header from inside the area is weak and Brad Guzan can collect.
Djilobodji has to run all the way back into the Sunderland defence now.
Sunderland 0-2 Middlesbrough
Already sub Jeremain Lens makes this Sunderland team look better than the one that was out in the first half.
His hard work forces Adam Forshaw into a mistake in the middle of the park, but Lens is lacking in vision when trying to play the ball forward into the path of Jermain Defoe.

Hugh Rodger: Simply incredible that United actually got money for McNair and Love. Absolutely dreadful today
Robbie Edwards: I give up ... It's just the same story every season. We finish the season strongly but spend no money and struggle again

Former Sunderland defender Gary Bennett on BBC Newcastle: "How are Sunderland going to get back into this game? Who is going to get hold of it? I can't see anyone who's going to do that."
Sunderland 0-2 Middlesbrough
Middlesbrough have found a decent partnership here...

That is the last meaningful act of the first half and the Sunderland supporters are not happy as they boo their team off the pitch.
Sunderland 0-1 Middlesbrough
Former Sunderland defender Gary Bennett on BBC Newcastle: "It's men against boys. Sunderland are all over the place and by the looks of it it could be three or four. There's still another half to go.
"It's going to be a long season."
Cristhian Stuani (44 mins)
Boro double their lead with a beautiful team goal.
Midfielder Adam Forshaw crafts a wonderful reverse pass into the feet of Alvaro Negredo in the box.
The Spaniard sells Jack Rodwell a dummy into next Sunday, which opens up the space. The ex-Manchester City man has the composure to roll the ball into the path of Cristhian Stuani, who picks his spot and caresses a finish into the roof of the net.
The Middlesbrough supporters go wild and so they should. Their side have picked Sunderland apart today.

Adam Jones: Based on the first 30 mins, think I could be watching 2 teams who gonna get relegated this year.
Steven Horlock: Sunderland are in serious trouble this year. A team made up of rejects, and no idea how Watmore is a professional player.
Dennis Ethan: Sometimes you got to question Moyes' decisions. Khazri is on bench. Bearing in mind he was phenomenal for Sunderland last season.

"Faster, faster," Middlesbrough boss Aitor Karanka shouts from the technical area.
His side have not seen much of the ball today, but have a decent spell in possession.
It finally goes towards Alvaro Negredo in the box, but the Spain striker's first touch is sloppy and the ball runs away.
Sunderland 0-1 Middlesbrough
Former Sunderland defender Gary Bennett on BBC Newcastle: "I can't understand that change. You've got Paddy McNair who plays centre-back. He's played there for Manchester United. Why doesn't he drop back alongside Papy Djilobodji and play centre-back?
"I hope Jack Rodwell can play centre-back. Sunderland have lost all shape. I would have put McNair at the back and Rodwell as the holding midfield player."
Sunderland 0-1 Middlesbrough
It is a change of shape for Sunderland. Steven Pienaar slots into the middle of the park and Jack Rodwell drops back to partner Papy Djilobodji.
The Senegal defender almost draws the home side level after trotting up the pitch for a corner, but his header from six yards out drops wide of goal.
Sunderland 0-1 Middlesbrough
No, John O'Shea cannot play on. He hands the captain's armband on to Jermain Defoe.
On comes free signing Steven Pienaar for his debut. Surely the South African is not going to play at the back?

Former Sunderland defender Gary Bennett on BBC Newcastle: "I have got to say that Donald Love is causing his own problems here. It's got to a be a concern for David Moyes down Sunderland's right side."
Sunderland 0-1 Middlesbrough
Despite being ahead, Middlesbrough have not had a touch in the opposition box yet.
Sunderland defender John O'Shea is down and currently taking treatment from the physio. It is a problem with his right leg. Can he continue?
