The Bhoys boss made a personal visit to check out Kozak playing for Villa’s Under-21 side, as he put in a two-goal performance to secure a victory over Derby County.
It was the forward’s fourth appearance at Under-21 level this term, following the long-term injury he suffered at the beginning of 2014, and it has been almost two years since he last played in the Premier League .
This term, his only senior appearance was as a second half substitute against Notts County in the League Cup.
Many believe that losing him will not be too much of a loss for Remi Garde, and Deila will fancy his chances of signing the striker.
However, given Villa’s current predicament, they would be foolish to get rid of him without at least giving him a chance in the Premier League in the coming weeks.
Jordan Ayew looks to be living up to his reputation after some early season struggles, but Rudy Gestede is clearly not the required quality for the top flight, and Kozak would at least offer Garde another presence upfront if he decides to select the Czech striker.
He is tall and good in the air, and in a front three of Ayew and Carles Gil, Kozak would get the service which his finishing skills need to be an effective forward. He proved in his short spell of fitness with Villa that he is a natural goalscorer, and goals are exactly what Villa need right now.
Kozak may not be of the quality needed in the Premier League, but he cannot be a worse option than the players currently turning out for the Midlands side, and Garde needs to give him a first-team chance before deciding to offload him to Celtic in January.
