Watford are likely to give new signing M'Baye Niang his debut at Arsenal tomorrow night.

The French attacker joined on loan last week until the end of the season but did not receive international clearance in time to feature at Millwall yesterday.

But Niang is available for tomorrow's Premier League clash and is set to be involved for Walter Mazzarri's side.

Hornets head coach Mazzarri said: “He is available [Niang]. He will probably come with us.

"He hasn’t been training a lot with the team but he is a player we can utilise in the game."

Another new signing Mauro Zarate is still suspended from a red card picked up in Italy which means he cannot play until the Burnley game this weekend.

Defender Jose Holebas remains out as he serves the final match of his suspension for picking up ten bookings.

Goalkeeper Costel Pantilimon is likely to be sidelined for three to four weeks after suffering a leg injury in the FA Cup defeat at Millwall.
