West Ham shareholder Daniel Kretinsky was photographed celebrating the Hammers European cup win in his native Prague last Wednesday.

Kretinsky also owns 40% of football club Sparta Prague where he is president and watched them crowned champions of the Czech League last month

Often referred to as the Czech Sphinx for his non emotional approach to business and dislike of the media limelight he clearly shows his passion when it comes to his football.

Earlier this season he was reported by match officials by entering the referees room at half time without permission to argue with the ref.

Sparta Prague have qualified for Champions League third qualifying round next season while West Ham have qualified for Europa League group stages

If Sparta fail to progress they could drop down to the Europa League play off stages and could potentially meet West Ham in the group stages if they progress.

UEFA rules say ‘No individual or legal entity may have control or influence over more than one club participating in a UEFA club competition, such control or influence being defined in this context as: holding a majority of the shareholders’ voting rights;

As Kretinsky holds 27% of the voting rights  for West Ham and 40% of the voting rights for Sparta Prague this is not currently an issue but it is a major obsitcle in the way of the Czech Billionaire becoming majority shareholder of West Ham. He is likely to remain minority share holder of both teams for the foreseeable future.
