Daryl Janmaat will be fit to return to Walter Mazzarri's Watford squad this weekend after recovering from a clash of heads which ruled him out of last weekend's game at West Brom.

Janmaat's training ground injury, sustained when challenging for the ball with Adrian Mariappa, has cleared up sufficiently for him to return to training on Wednesday of this week ahead of tomorrow's clash with Everton at Vicarage Road.

Elsewhere, Isaac Success is continuing his return to fitness, after being named an unused substitute at the Hawthorns last weekend.

The pair are the only two players currently undergoing recovery who will be fit enough to make Mazzarri's squad tomorrow, although Miguel Britos and Valon Behrami will also return from their suspensions.

The Italian head coach said: "Janmaat is available. You will see the starting 11 once we are there but he is available and you will see. He has trained for two days since he recovered.

"Success is getting better even though he does not have the 90 minutes in his legs."

With forward options at his disposal in the form of Success, Odion Ighalo and Jerome Sinclair in addition to last weekend's starters, Troy Deeney and Stefano Okaka, it has been difficult for Mazzarri to shuffle his pack to give each player the minutes they may have needed so far.

To that end, Sinclair's injury-time debut in the West Midlands was only his first appearance under the head coach - and Mazzarri admitted it was difficult to strike the perfect balance with his team's strikeforce.

He said: "His Success’ best moments obviously came was when he was playing, but we cannot play him if he is injured.

"Sinclair is different, if I put Sinclair on you have to take away one of Deeney, Okaka and Ighalo and I have to make these decisions because it gives the team more equilibrium.

"He is very good and has good skills, but he can improve physically. You go on the pitch only with 11 players, and also Amrabat can play as a striker. You cannot play with four, so this is the decision I have to take."
