Paul Merson believes that Chelsea are set to play out a goalless draw with Arsenal on Sunday – because Diego Costa isn’t likely to be fit.

The Blues head to The Emirates 10 points clear of their London rivals as they look to secure a victory to move them closer to winning their first Premier League title since 2010.

The Gunners have been in fine form in recent weeks and have won their last eight Premier League games in succession to move them up to second place in the table.

However, former Arsenal man Merson believes that a goalless draw is the most likely result when the two London sides do battle at Emirates Stadium on Sunday.

Merson told Sky Sports: “This game all depends on Diego Costa. If Costa’s fit it’s a different game, but if he ain’t fit I can’t see any goals.

“Tactically, Mourinho can go somewhere and make it very difficult and Arsenal have that tendency to shoot themselves in the foot if it is tight and Chelsea are defending well.

“Last week, Chelsea had 30 per cent of the play at home but Man Utd never looked like scoring. They never looked like scoring. If that happens in this game, Arsenal will get frustrated and they will let in Chelsea. But I think Mourinho will go there, make sure they don’t lose, and that will be it.

“If Arsenal did win, the difference between them would be seven points. Football’s a funny game: Chelsea go to Leicester on Wednesday night and who’s to say Leicester don’t win that by a fluke goal, Arsenal win their game in hand, and it’s four points?

“But I’d be shocked if Chelsea didn’t win the title from here with the manager they’ve got. Tactically, he’s too cute.

“The last two games they’ve won 1-0 and probably haven’t had five shots. But they won both games – anybody else wouldn’t have won those games and that’s where the points mount up.”

Chelsea need just six more points from their remaining six games to secure the title this season.

Arsenal are looking to end the season with a trophy again after they set up an FA Cup final clash with Aston Villa at Wembley next month.

We can still mangle these Mancs, whether they’re Sky Blue or Devil Red…

By Woolwich 1886

Once Sunday began with an improbable, last-ditch win for City at Liberty Stadium, we might be excused for mailing it in a bit at Old Trafford. After all, Yaya Touré’s winner all but cinched the belt on second place, and what else is there Arsenal to play for but third? For 75 minutes, we played in such a way that a comparison to dog food would be insulting to it, not us, and we still emerged from a stadium in which we haven’t won a Prem match for how long I don’t dare mention it (okay, September 2006).

It’s not the win we clamored for, but it’s a result that sees us batten down hatches and all but dare Man U to overtake us anyway. Like it or lump it, that’s a far-cry better than we might have hoped for when the first half of the seasonunravelled unfolded.
