Aston Villa's financial restraints in the January transfer window have been the subject of several questions sent in via our 'Ask about Aston Villa’ form.
BBC Sport's football reporter Nick Mashiter addressed these talking points in a wider piece for the website and we have pulled out the most relevant sections:
Financial restrictions have already impacted Aston Villa's January business. The club missed out on signing Conor Gallagher, who joined Tottenham.
Forward Donyell Malen, Villa's second top scorer this season, has been sold, while squad depth and growing injury worries have added to Emery's problems.
So does Villa's season hinge on the final two weeks of the transfer window?
It is the balancing act Emery has to get right while Villa walk the financial tightrope, which has harmed them in more ways than one.
Gallagher would have at least eased a growing midfield injury crisis, with Emery losing John McGinn on Sunday while he was already sweating on Boubacar Kamara's fitness and Amadou Onana already out.
There are also no plans for Leon Bailey to return from his loan at Roma, despite his struggles.
This month Villa have signed Gremio winger Alysson and 17-year-old striker Brian Madjo from Metz – both with a view to the future.
Villa tried to change the profit and sustainability rules (PSR) in 2024 but failed to get the loss limit raised from £105m to £135m over three years after the proposal was rejected at the Premier League's AGM.
Co-owner Nassef Sawiris previously said the rules "do not make sense" because they cement the bigger clubs' powers. To comply, Villa had to sell, and Jacob Ramsey went to Newcastle for £40m in the summer, the academy graduate banking pure profit for Villa.
Yet Villa had been sanctioned by Uefa in July, along with Chelsea, and fined £9.5m for breaching financial rules.
With Villa eight points clear of fifth-placed Manchester United in the Premier League, a return to the Champions League next season is increasingly likely, which would almost end their financial concerns, according to finance expert Kieran Maguire.
