The Villans are undergoing something of a rebuilding process after the disaster that was their relegation from the Premier League last season.
Up until last week they had been relatively quiet in the transfer window before paying big money to sign Ross McCormack from Fulham.

That has not allayed some fans’ fears though, especially when they have had to watch rivals such as Newcastle United have strengthened heavily.
Yorke is one of those concerned, saying he wants to see his former side being more aggressive about their intent.
“They’re not making too much noise, although they obviously went out and spent a lot of money on a striker,” he told talkSPORT.
“Whether he can be the solution I’m not sure. I think that for a team that has just been relegated, they need to make more noise and show their intent. I’d like to see a little bit more aggressiveness.”

It remains to be seen whether Villa will make further moves in the remainder of the transfer window.
There is no denying that they need to add further quality if they are hoping to compete at the top end of the Championship this season.
With £14 million paid out for McCormack already though, it would be surprising to see them paying big money on other signings before the end of the transfer window.
