Indeed, the pundit believes the defender's challenge that earned him his sending off was borne out of frustration and 'designed' to take his opponent out.
Collins wasn't the only West Ham man to err against Watford, of course, but Jenas felt his challenge was 'very, very bad' and that the 32-year-old should have kept his emotions in check a little better.
Jenas told Match of the Day: "To compound such a poor display, that is a very, very bad challenge from James Collins. He deserved to go.
"He’s obviously not happy with how [Odion] Ighalo picked his runs out during the game as that is a challenge designed to take him out."
Collins has been heavily praised of late after coming back into the Hammers first team and excelling against different opposition.
Here, though, the 32-year-old did not respond well in the second half as West Ham capitulated at Watford.
James Tomkins, Andy Carroll and more were also at fault during significant events but Collins will now serve out a suspension, meaning his moment of madness will cost West Ham even more.
