The pressure on Ole Gunnar Solskjaer is mounting following Manchester United's 0-0 draw against Wolves in the FA Cup on Sunday.The Red Devils produced an uninspiring display at Molineux and failed to record a single shot on target.Solskjaer made several changes to his side, giving starts to youngsters Brandon Williams and Tahith Chong, but supporters are still giving him a rough ride, with increasing calls for his departure on social media.A petition titled ‘Get Ole Gunnar Solskjaer out of United’ has attracted more than 1,000 signatures, and you’ll see a slew of #OleOut tweets if you enter his name on Twitter.The Norwegian had a positive impact upon his arrival in 2018 but that 12-match unbeaten streak seems like a long, like time ago now.

• Solskjaer 'copies' Arteta
• Williams proves he should start
• Solskjaer hits back at Van Persie

In the months since, Solskjaer’s lack of tactical nous has been exposed and he doesn’t look suitable for the job.

Managers like Pep Guardiola, Jurgen Klopp and Mauricio Pochettino all have a style that is easily identifiable. Even Mikel Arteta’s philosophy is becoming clear after three games at Arsenal.

That’s not the case at Old Trafford. They were effective on the counter-attack in the early days under Solskjaer but that’s proven not to be a sustainable approach.

And a clip of Solskjaer on the touchline during the draw against Wolves has left United supporters very confused about what his message actually is.

The camera cut to Solskjaer in the 90th minute and he could be seen gesturing to his players, moving his hand around in a circle motion.

Some more swift gestures follow but it’s very hard to understand what they mean.

Man United fans have reacted to the clip.

Perhaps it was clear to Man United’s players what Solskjaer wanted. But he hardly seemed convinced in what he was really doing.

Just look at this video comparison of Arsenal’s Arteta and Solskjaer both giving instructions during Wednesday’s match at the Emirates.

The Spaniard’s message is clear and his delivery is confident.

Some even thought that Solskjaer was copying Arteta.

A tough run of fixtures, starting with Manchester City in the League Cup on Tuesday, could make or break Solskjaer.
