He said: "I think they just wanted it more. You could tell they wanted it more. You could sense that from the kickoff. It was an uphill battle towards the end there.
"Like I said before, this isn't Arsenal at this moment time. We felt we had gotten out of that little patch, and hopefully we haven't been dragged right back into it. But judging from that performance tonight, it looks like [we have]."
Last night Christian Benteke wanted it more than Gabriel. But that lack of courage has been evident on several occasions this season. Ashley Williams wanted it more than Mesut Ozil. Eden Hazard wanted it more than Francis Coquelin. Craig Dawson wanted it more than Alex Oxlade-Chamberlain. Etienne Capoue wanted it more than Aaron Ramsey.
When the going gets tough, the Arsenal players down tools. At times calling them cowardly feels too kind.

Who are the favourites to replace Arsene Wenger at Arsenal?
And the anger felt by the Arsenal fans who loudly chanted ‘you’re not fit to wear the shirt’ at the players was matched by the eviscerating words of Jamie Carragher in the Sky Sports studio.
He said: "I just think, from top to bottom this club is not right. The Wenger talk of staying or going. The contracts with Sanchez and Ozil. They've been nothing short of embarrassing since the contract talk started.
"We always criticise Ozil, and I'm not his biggest fan. But I think Sanchez has been awful the last couple of months. Certainly not looking like they're playing for contracts. It's looking like they're playing to get away.
"They're talking about how much the figure is going to be. Arguing about money.
"Their performances since the talks have been embarrassing. They're supposed to be the star men of this team. They’ve been bought to take Arsenal to titles, to the Champions League and they've been nowhere near good enough."
Theo Walcott's comments are a concern for Arsenal

Yet it’s Walcott’s comments which are most troubling.
The England international is very well spoken but it is also very clear he was one the players who listened most intently during the 'How to deal with the media' powerpoint presentation.
After a humiliating defeat, the last thing the fans want to hear is the players didn't try.
For who's benefit are those comments? Is he calling out his team-mates? Is it a swipe at the manager's lack of motivation?
Walcott himself was as ineffectual as paper in water. He offered little threat to Jeffrey Schlupp and could have no complaints about being hauled off.
With Per Mertesacker, Laurent Koscielny, Santi Cazorla and Petr Cech all absent, Arsenal were down to their fifth choice captain in Walcott.
Arsenal's Mesut Ozil looks dejected after the match
He's now played more games than Thierry Henry under Arsene Wenger in the Premier League and his consistent inconsistency is symptomatic of the failings which have cost the club over the last decade.
Impressive when confident, absent minded and weak when under the cosh.
Last night at Selhurst Park felt different with how the away fans went after the players. Not even the likes of Sebastien Squillaci were given such brutal treatment.
Wenger may feel it's not the right time to discuss his future but he's allowed unease and uncertainty to suffocate the club.
There's no doubting his love for Arsenal but Wenger is clearly the problem, not the solution.
And the sooner he realises this, or the board puts him out of his misery, the quicker Arsenal can start to move on.
