Redknapp wrote a column in the Telegraph suggesting that Villa’s season had been ‘pathetic’.
However, Keys felt that Redknapp was in no position to comment, as Queens Park Rangers had a similarly disastrous campaign in the Premier League while he was in charge.
“What about 'Arry again today? 'One word to sum up Villa's season - Pathetic' screams the headline on his column in The Telegraph,” Keys wrote.
“I’m sorry - who was it won four of 22 games at QPR, whilst taking them down? Who left the club with the lowest win percentage of any QPR manager in the P Lge - just 19%? Where is Yun Suk-Young, one of the signings taken in by 'Arry during his time at Loftus Road? Tak Ben Haim? Chris Samba?
“How many clean sheets did they keep with Samba in the team? Just the one. How much was spent in the 2013 January window - £21.5m - not including 'undisclosed' fees. QPR went down with 25 points. I call that 'pathetic'. Honestly. The man has no shame - and a very short memory.”
Villa have won just three Premier League matches all season, and they are now destined to be relegated.
The Claret and Blues have not shown much fighting spirit throughout the campaign, and plans have already begun for life in the Championship.
They will take on Redknapp’s former QPR side next season, as they still look to find their feet in the second tier.
Rangers have endured a disappointing campaign this time around, with the club still looking to clear out some of the players that Redknapp brought to Loftus Road during his time in charge.
