Aubameyang has scored just four Premier League goals so far this season and Arteta wants him needs to step up.

Manager Mikel Arteta is hoping Arsenal captain Pierre-Emerick Aubameyang can improve his goalscoring tally.

The Gabon international missed an open goal during the Gunners' 2-0 win over Newcastle United on Saturday and has failed to score in his last four matches.

It is obvious if Arsenal are to have a successful campaign, they’ll need the 32-year-old firing on all cylinders.

And, Arteta concurs as he hopes Aubameyang’s 'scoring contribution' improves.

‘Well the form of Auba is always going to be related to the goals that he scores,’ Arteta told reporters ahead of Arsenal’s trip to Old Trafford.

‘He’s doing many other things apart from scoring goals, but obviously we need that contribution because his goals are critical to our success and that’s been showing in the last few years.

Arsenal's Gabriel Martinelli admits he is patiently biding his time.

‘That has to be his aim, to continue to do all the things he’s doing and then, in the right moment, put the ball in the net.’

Arteta also lauded Manchester United's appointment of Ralf Rangnick, labelling the German as a 'really interesting person'.

Rangnick's arrival was confirmed on Monday but awaits his work visa to be confirmed, however, as things stand, caretaker manager Michael Carrick will take charge of the Premier League clash tomorrow.

'He's been one of the top coaches,' Arteta said in his press conference on Wednesday.

'He's made some radical changes in some areas and is a really interesting person in the football world and a really interesting appointment for the football club.'

Arsenal currently sit in the fifth spot in the English top-flight table and could be eight points clear of United if they beat the Red Devils.

The match at Old Trafford will be the first game this season without Ole Gunnar Solskjaer at the helm.
