'What's the shape?'published at 16:30 British Summer Time 26 April 2015
We wondered how Chelsea would line up today and so far it's basically four at the back, Nemanja Matic and Cesc Fabregas in midfield and then four men freestyling.

We wondered how Chelsea would line up today and so far it's basically four at the back, Nemanja Matic and Cesc Fabregas in midfield and then four men freestyling.

"Another penalty. Jose will be checking the minutes before his post-match press conference."
Jose Mourinho's opinions on referees and the perceived lack of penalties his side get may be about to get another airing.

"Santi Cazorla hangs a leg out but he pulls it back at the last minute. There is a dive by Cesc Fabregas and it's a booking. There is a small amount of contact, but Fabregas made a lot out of it."
Cesc Fabregas booked for diving!
That will make the Arsenal fans' day! Cesc Fabregas spins into the box, he goes down about a yard away from referee Michael Oliver - and he is booked for a dive! Santi Cazorla was the man making the challenge. Looked like a knee on knee contact to me...
Oscar is back with us after a rinse with the magic sponge. Cesc Fabregas has a shot well charged down, Chelsea enjoying a spell of decent pressure.

"I think it's a penalty when Ospina absolutely wipes out Oscar. If it were outside the box it would be a free-kick. It's a penalty, 100%. Mourinho is asking the fourth official that question now. I'm sat here confused as to why it is not a penalty"
BBC Sport chief football writer Phil McNulty at the Emirates
"Lively, physical start and referee Michael Oliver is happy to let plenty go. Chelsea manager Jose Mourinho already showing some signs of discontent, calling Cesar Azpilicueta to the technical area for a lengthy chat demanding adjustments then some frantic waving to demand his defence do not get pinned too far back."
Isa Zina: I'm an Arsenal fan but I would never boo Fabregas, he was our captain and wanted to return, it's not his fault Wenger said no!
Andrew Soar: I really wish we didn't boo Cesc. He never let us down and only left for his hometown club
Liam Kennedy: Arsenal fans booing Fabregas when they didn't want him back. Short memory

Cesc Fabregas gets his head up and lofts a brilliant, quarterback pass over the top. Oscar is in on goal, he chips it over the onrushing David Ospina, and the keeper absolutely cleans him out.
Should that be a penalty?! Nothing is given and Hector Bellerin is able to head Oscar's shot off the line. Oscar needs some treatment, he got wiped out there. Jose Mourinho can laugh about it...
When Arsenal get it right they remain box office viewing. A thrilling pattern of one-touch stuff sees them move the ball swiftly and sharply from left-back to the edge of the area but Branislav Ivanovic defends it really well, mugging Mesut Ozil and clearing his lines

"There's no sign of Chelsea parking the bus here today. They're passing it around nicely."
Not sure if Jermaine read the comment from Phil a few moments ago..
Great skill from Olivier Giroud as he holds the ball up alone, spins a defender and chips it over the head of John Terry but Terry reacts well to head it clear. Arsenal on top - that pattern won't change and it won't bother Jose Mourinho.
There are lots of things, and people, I'd like to ban in football Phil but for some reason I just don't have that sort of power. Alexis Sanchez with extraordinary pace almost catches out Thibaut Courtois but the Belgian just about gets a clearance away.
Phil: Dear BBC, please ban the plastic armchair fans from using the phrase "park the bus". These so called fans are clueless on tactics and strategy and just like gung ho kick and rush
James: Jose Mourinho will be trying to keep his record over Arsene Wenger intact. He will not want to give Arsenal any encouragement for next season.
Chris Newman: Well here it is - the battle between England's two quietest sets of fans...

Branislav Ivanovic has a lengthy chat with referee Michael Oliver and is lucky not to be booked after clattering Alexis Sanchez. Arsenal not able to settle into their rhythm.
If this game stays 0-0 Chelsea will end the day 10 points clear of Manchester City. They will not be able to win the league against Leicester on Wednesday though.
Oscar takes a tumble right on the edge of the box but that's not a penalty says ref Michael Oliver. A 'coming together'.

"Oscar is in the middle up top. With Hazard left and Ramires has picked up the right side position. It's Matic and Fabregas in the middle of midfield - if you hear boos it means Fabregas is dictating this game."
The Arsenal fans have quickly got bored of jeering Cesc Fabregas. Alexis Sanchez has been lively in the red and white so far, winning a free-kick from Branislav Ivanovic but that came to nothing.
The mention of Chelsea's 17-year-old prospect Dominic Solanke has got a few of you talking.
Scott Carnegie: I am slightly disappointed that Solanke is not in this Squad, was really hoping he could make it.
Nene Odonkor: Solanke is good but inexperienced for such a high tension match like this
Tom Neale: Dominic Solanke will be playing in the FA Youth Cup tomorrow, even at his age I think 2 games in 2 days is too much.
Well, that's that then...
