Dielna arrived at Wednesday last summer, signing from Olympiakos on a free transfer.
The 27-year-old defender spent his debut season in English football as something of a rotation option at Hillsborough, making 25 appearances in all competitions, and scoring one goal.
Able to play all across the defensive line, the former Sedan, Ajaccio and Loriet player frequently appeared in the centre and to the left of the back-line, and he was an acceptable performer - if fairly average.
However, this has not lowered interest in him, and French media outlet FootMercato claims that he is in talks with Aston Villa to move to the club this summer, with 'negotiations proceeding well'.
He is said to be in advanced talks with the Premier League club, with Tim Sherwood keen on bringing him to Villa Park as his second signing of the summer - following the permanent deal for Scott Sinclair.
It would be a surprise deal, with Dielna hardly impressing at Championship level - let alone showing the ability to make the step up to the Premier League - but clearly Sherwood has seen enough to be impressed by the defender.
His versatility is useful, and adding reinforcements to the defensive unit will be of vital importance to Villa this summer, and it looks as if Dielna is well set to move to the Birmingham-based club with talks progressing well.
