The latest is Romaine Sawyers, whom Smith picked up following his release from West Brom, firstly at Walsall, before taking the midfielder with him to Brentford.
Sawyers is well thought of and an important player in a Brentford side that has gone into a nosedive since the change of management.
Sawyers, to his credit, has worked his way up the game having been discarded by Smethwick, accumulating over 200 league appearances and is now Captain at Griffin Park.
However, the question would ultimately be exactly where would he fit? What gap does he fill?
Villa, whilst having had some injuries in the middle of the park, do have an array of midfielders.
Indeed, we have both balance and variety in our ranks that ranges from Birkir Bjarnason to Glenn Whelan.
One element that might be advantageous would be that Brentford find themselves with a player inside the last 18 months of his deal.
