Massimo Cellino is the chairman of Leeds at the moment, while Vincent Tan currently owns Cardiff City.
Collymore is not a fan of either Cellino or Tan, and he has made some harsh comments about them.
The former England international striker has also criticised former Birmingham City chairman Carson Yeung and Aston Villa chief Randy Lerner.
“He (Lerner) ruined Cleveland Browns too in the NFL, to the point where he sold up and went into hiding,” Collymore wrote on Boylesports.com. “He’s hoping the same will happen at Villa but big clubs in the NFL where there’s no relegation don’t come cheap and still have top flight cache.
“Villa are relegated, have a poor playing squad and a manager who probably won’t be there come May, so who is going to buy?
“A Cellino? A Carson Yeung type? A Vincent Tan? Men who prey on clubs for the short term. Never for the long term, to take care of and to provide stability and grow, so it’s incredibly worrying times for the club.”
Villa are at the foot of the Premier League table at the moment with just 16 points from 26 matches, eight points behind 17th-placed Norwich City.
Leeds, Cardiff and Birmingham are currently in the Championship. While the Whites are in the bottom half of the table, the other two teams are doing relatively well and could potentially return to the Premier League as early as next season.
Birmingham are seventh in the league table, just three points behind sixth-placed Derby County, while Cardiff are only five points off the playoffs.
