The Magpies welcome the Owls to St James' Park on Wednesday evening.
The centre-back duo of Fabricio Coloccini and Chancel Mbemba have had their promising moments, but have looked out of sorts in the last two games.
Coloccini, in particular, seems to be struggling and his status as club captain shouldn’t prevent Steve McClaren reshuffling the pack if necessary.
Lascelles arrived highly-rated from Nottingham Forest and will be hoping to stake a claim for first-team consideration in his second appearance of the season.
19-year old Aarons is one of the brightest young talents at the club and calls are growing for him to be given a starting berth in the Premier League, after several insipid displays from his more senior colleagues.
He should feature from the off against Sheffield Wednesday in midweek and it will be a chance for him to demonstrate what he can bring over a 90 minute period, as opposed to the substitute appearances he has seen so far.
Siem de Jong
Similar to Aarons' case, fans have been clamouring for De Jong to start in the league, and as one of the Magpies’s most naturally gifted attacking midfielders, it is easy to see why.
The Dutchman has the ability to give Newcastle that extra guile in advanced areas and must use tomorrow’s clash to leave McClaren in no doubt as to the merits of him starting against Chelsea this weekend.
