Collison was commenting on James Tomkins, who signed a new deal last month as a reward for the progress and form he’s shown so far this season.
“He loves playing football. He can lose his head now and then but he's been magnificent this year and it was great to see him being rewarded with his new contract,” said Collison.
It’s important for any central defender to be able to show aggression, but he has to come in a controlled way.
Tomkins, and any other West Ham player, may feel as though they are about to ‘lose it’ but they can’t allow that frustration and the red mist to get the better of them, leading to a poor decision.
Tomkins does deserve some credit, because he’s now a very experienced Premier League central defender.
Sam Allardyce knows his character and Tomkins understands the identity of the club and what’s expected of him every time he steps out to represent the club.
The West Ham defence needs to be rock solid over the rest of the season for the Hammers to force their way into the Premier League’s top eight and there’s no reason Tomkins won’t be integral to that.
