Former Arsenal midfielder Paul Merson believes Chelsea will get it right from a tactical standpoint this weekend.

The Blues head to the Emirates Stadium on Sunday to take on Arsene Wenger's in-form Gunners but Merson is of the belief that the Premier League leaders, under the guidance of Jose Mourino, will produce a tactically sound 90 minutes to get a vital draw.

'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,' Merson wrote in his pre-game analysis for Sky Sports.

'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.

'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.'

Merson predicted a 0-0 draw for the clash between Arsenal and Chelsea.
