Walter Mazzarri says Mauro Zarate was in tears after being stretchered off against West Ham United but the Watford head coach hopes the injury is not too serious.

There was a long stoppage at the end of the first half as Zarate was taken off against his former club with a knee injury.

Speaking after tonight's 1-1 draw at Vicarage Road, Mazzarri said: "We will check in the next hours and most probably we will know tomorrow. But I saw him with a lot of pain. He was in tears so let’s hope it’s nothing too bad."

The Italian added: “If you see the game I saw he was not completely ok because on the first knock he felt something but he kept telling me to wait and not make the change.

"He wanted to stay on the pitch but it’s true there were two occasions where he hurt his knee."

Daryl Janmaat also went off with an injury in the second half after a problem with his abductor.

Mazzarri said: “On top of that I knew that between the first and second half Daryl Janmaat was having some problems with his abductor. We didn’t know if he was well enough to continue.

"But he decided to stay on for the second half and again tomorrow we will check and we are training so we will see tomorrow."

The Hornets led through a Troy Deeney penalty but Mazzarri was frustrated after the Hammers deservedly earned a second-half equaliser.

The Watford boss said: “Of course we are committing too many silly mistakes especially in the second half.

"We cannot allow them to score from a counter-attack especially when we are winning 1-0. But even at the end we could even have won the game.

“Anyway I want more continuity and intensity from my team and hopefully, if it’s possible, for the whole 90 minutes but at least for 70 or 80 minutes."
