And the presenter has also commented on Sherwood having 'lost his tongue,' questioning whether he knew he could lose Delph for such little money when he took over at Villa Park.
Keys wrote in his blog: "Tim Sherwood has lost his tongue, as well as his best two players, so I'm not surprised. Unless he can get some decent replacements in Villa are in for another struggle.
"I wonder if he knew Delph could walk away for such a pittance when he took over?"
Are Villa doing enough?
Keys isn't the only member of the media to remark on Sherwood's recent silence but it could simply be the mark of a maturing manager who is eager to get on with a difficult job at hand.
Whether he and the rest of those responsible at Aston Villa are doing enough remains to be seen but they have recruited already, with Idrissa Gueye being brought in as what looked like a Delph replacement at the time (two U-turns later and that still appears to be the case).
Sky Sports also report that Villa have had a bid accepted for striker Jordan Ayew. The Midlands club certainly aren't sitting back, then, but it will simply be whether those they sign are adequate enough replacements. In that sense, Keys is right.
