The 1-0 loss was a disappointing result for Tim Sherwood’s side as they more than matched up to Louis Van Gaal’s side throughout the game, but failed to properly test goalkeeper Sergio Romero.
They looked short of attacking threat throughout the game though, and with Christian Benteke having left for Liverpool this summer as well, that will be a concern for them moving forward.
And Souness says they must find a way of being a threat, even if that involves changing how they play.
“They carried no threat. Sherwood will sleep well but they look limited,” he said to Sky Sports.
“Villa didn’t really carry any sort of threat, and that will be a concern. They’ve got to find some sort of way of playing that makes them more threatening than they were tonight [against Manchester United].”
Home form an issue
The former Premier League boss also believes they must look to improve their home form if they wish to stay in the Premier League.
Sherwood’s side had one of the worst home records in the division last season, as they lost eight times out of their 19 games, winning just five, meaning they had the 17th worst record at home in the entire league, with relegated QPR even being ahead of them.
Given they were also 14th when it came to away form, it proved a dangerous partnership as they flirted with relegation for most of the campaign, and Souness says they must make Villa Park a fortress to avoid that happening again.
“Winning here [at Villa Park] is an issue, if you’re going to survive, generally it means you’ve got good home form,” he added.
