he was robert Horry of futbol 4 teams 4 titles 1 uefa champions league

mostly i will remember that he was paying 5000 euros each day for staying in hotel in Milan

There is list of futbol players that regret of leaving United.

I will put in there Cristiano but i will not put there David he is not only commercial player but legend
only player that also won 3 champions league with 3 teams and is still active its Seedorf.
