The two sides drew 2-2 in a highly controversial game on Sunday.
In a highly contentious affair on Sunday afternoon, the two sides played out a 2-2 draw in which the attention was firmly upon the officials.
That came after Andy Moss was forced to make several big decisions, including two penalties and a red card for Jamie Vardy.
Indeed, he was kept on his toes from the start of the game as the tackles flew in from both sides and they tussled at almost every corner.
And as far as Keown was concerned, the Hammers were animalistic in their approach, but says that is a compliment, adding they are the best at turning the penalty area into a battleground.
“So soon after the demoralising FA Cup defeat by Manchester United, they were back on their A game. It was as if they were the team going for the title.”
“And they are the best attacking team in the Premier League at creating a battleground in the penalty box, thriving off of Dimitri Payet’s wonderful set plays. They are very clever at it.”
Keown’s praise will be little consolation to West Ham as their Champions League dream slips away.
They can feel aggrieved, having been on the end of a number of controversial decisions in recent weeks that have cost them crucial points.
As a result, they currently sit sixth in the table and seven points behind Manchester City, and will need a serious change in fortune if they are to make fourth their own.
