Walter Mazzarri believes a post-match altercation between Troy Deeney and Stefano Okaka is nothing to be concerned about.

The alleged disagreement came at the end of a dramatic 4-3 defeat at Stamford Bridge, which had seen Watford battle back from 3-1 down to draw level, only to be denied at the last by Cesc Fabregas’ strike.

Mazzarri played down the significance of the coming together and insists the two strikers have a strong relationship.

“I didn’t realise [it had happened] to be honest. I was angry with the referee because there were two fouls before their goal which penalised us,” Mazzarri explained.

“There was a moment where we could have scored with Behrami and Janmaat before then where we could have won the game. This didn’t happen so we were all very nervous.

“They (Deeney and Okaka) are friends, they are always together and they joke with each other”

Mazzarri has called on his players to show greater fight in recent weeks, and even went as far as to suggest disagreements on the pitch are a sign of a strong character which he is looking to foster.

He said: “Nobody told me anything about what happened. I also want players with character, players to talk to each other on the pitch and off it.

“I will investigate tomorrow, but I do not think there was anything in it.”

Watford’s comeback, which saw them become the first team to score three goals at Stamford Bridge this season, came on the back of a 10 hour plus wait for a goal away from home.

With this in mind, Mazzarri was pleased with his players’ efforts at the newly crowned champions in spite of the scoreline.

He said: “I am proud of my squad and proud of my team. I am still evaluating the team for next season and there were some positives as well as some things that were not that positive.

“It was a good game and I am proud of my team.”
