Key defensive duo set to miss out for Watford

Kaboul was forced off with a hamstring injury during the 2-0 win at Southampton last weekend and has failed to recover, while Prodl is still carrying a knock sustained while representing Austria on international duty.

Craig Cathcart (knee injury) and Miguel Britos (suspended) are also unavailable but Marco Silva singled out Kaboul as the player the Hornets could miss the most on Saturday.

"He knows my idea and is a player with fantastic leadership. He's an important player in our squad but now is the moment to find another solution," Silva told the club website.

Silva could call loan signing Molla Wague into the squad for the first time to potentially partner Christian Kabasele or Adrian Mariappa in central defence.

"Of course (he comes into contention)," Silva said of the 26-year-old who arrived on a season-long loan from Udinese and has not played for Watford yet.

"It's not the best way, as he only worked with us since last Friday. Normally we like to give him time to know our style of play, our idea.

"Maybe we don't have time for that. Between him, Mariappa and Kabasele, I have to choose the centre-backs..."

The Hornets boss could also call on midfielder Roberto Pereyra who has missed three games this season while defender Kiko Femenia has recovered from a head injury and returned to full training. 

Watford, who have managed eight points from four games this season, have not won against Manchester City in the Premier League, losing four of their last six meetings.

City have also made a strong start to the season, collecting 10 points and are behind their rivals and early leaders Manchester United on goal difference.
