Watford manager Walter Mazzarri insists Nigerian striker Odion Ighalo's lack of goals this season is not a concern.
Having found the net 17 times last season, Ighalo has scored only once for his club in the 2016/17 campaign.
But Mazzarri believes things will soon fall into place for the Hornets marksman.
"He still has confidence because we as a team have confidence in him. There are periods where players are more in form than others.
"But we believe in him and it is just a matter of him scoring. Mainly what I ask from my forwards is not to score but to play well," the Italian told the Daily Star.
Ighalo was not part of the Super Eagles side that won away in Zambia in a World Cup qualifier last week, but instead travelled to Nigeria to attend to family matters.
Having only returned to England a couple of days before his club's clash with Middlesbrough at the Riverside Stadium on Sunday, Mazzarri admits he is pondering whether or not Ighalo will start the game.
"Of course he came back from Nigeria two days ago so it is very difficult to prepare," Mazzarri added.
"I have four forwards and various options, and will make a decision later."
