"He's holding his back, is that the last time we see David De Gea here at Old Trafford in a United shirt? It gives us a great opportunity to see Victor Valdes for the first time. Steve Bruce will be looking at this for next Sunday and thinking this is great news for him. He was player of the year two years on the run, but it goes for something at this football club when your player of the year for two straight years is your goalkeeper."
Phil Johnson:, external Painfully obvious that United have no pace in the back 4. They need to spend some money there as well this summer.
David De Gea heads down the tunnel. A clap to the Stretford End. Was the a clap to say, 'thank you and goodbye'?
Oh dear, has David De Gea made his farewell Old Trafford appearance? Victor Valdes comes on for his Manchester United debut.
Marcos Rojo also goes off to be replaced by Tyler Blackett.
Concern for United as David De Gea is on the ground at the moment...
Theo Walcott and Jack Wilshere come on.
Off go Hector Bellerin and Santi Cazorla.
What can the two Englishman do?

"It's that run again from Aaron Ramsey, getting in on the blind side of Marcos Rojo, Ramsey then lifted it over David De Gea but Rojo managed to just about get there."
It's there...or is it? NO!
Aaron Ramsey breaks clear and chips the ball over the onrushing David De Gea. The ball is heading into the net, but Marcos Rojo scrambles back to hook the ball to safety. That's three clear-cut chances now for the away side.
Fleeted-footedness from Marouane Fellaini to spin away from a challenge, nicely done. United monopolising possession at the moment, but can't find that killer pass to unlock the Arsenal defence.
"20 times, 20 times Man United," sing the home crowd.
Mesut Ozil swings in a free-kick from the left after being brought down by Robin van Persie...
...but it's straight out of play. Got to do better.
Shane Daly:, external Well..........I don't think Falcao will be at United next season.........bye bye (world's smallest violin)
Santi Cazorlaaaaa! Oh dear. The Spaniard gets his volley all wrong and the ball dribbles into David De Gea. He was free at the back post, in a similar position to fellow countryman Ander Herrera but Cazorla cannot apply the finish.
Arsenal getting chances now..
Phil McNulty
BBC Sport chief football writer at Old Trafford
"The standing ovation afforded to Falcao from Old Trafford seemed motivated by sympathy for a striker who has given it everything today but once again come up short. The waves to the crowd may carry significance as it is hard to see what hard evidence he has given Louis van Gaal that might persuade him to complete a permanent deal for the Colombian."
Arsenal growing in the game now. Alexis Sanchez is through on goal, but Marcos Rojo stretches to clear the ball.

"Pathetic defending from Marcos Rojo, totally the wrong side of Olivier Giroud but then a great save from David De Gea. I'm not sure about Rojo yet."
CHANCE! Mesut Ozil, the £42.5m man, finally works some magic and find Olivier Giroud. beautiful turn from the Frenchman who leaves Marcos Rojo for dead, but his shot is weak and David De Gea can save with his feet. Should have scored. Should now be level.
"Boooo," from the Arsenal fans.
Former Arsenal man Robin van Persie comes on to replace Radamel Falcao. A wave goodbye from the Colombian. He's not happy. Looks like he's off.
Liam Grayhurst:, external The players respect Wenger but they don't fear him, think it's ok to just turn up and get rewarded with a FA Cup final place.
Antoine V.:, external Uhm... Looks like Arsenal want income from that Champions League qualifier... Like against Swansea, they don't seem bothered.
You would think that the longer this goes on, the slightly happier Arsenal will be. They have been extremely poor today and will be confident of nicking an equaliser late on.
Aaron Ramsey breaks forward and finds Mesut Ozil with his pass, but the German's lay-off is awful and United get the ball away. What does £42.5m get you nowadays?
