Marco Silva believes both Kiko Femenia and Richarlison need time to adapt to life in the Premier League after enjoying varying degrees of success on debut.

The duo were forced on during Watford’s 3-3 opening day draw with Liverpool after injuries to Roberto Pereyra and Daryl Janmaat.

While Richarlison impressed in flashes, providing the assist for Miguel Britos’ late leveller, it was a testing afternoon for Femenia who was found out of position on occasion.

Silva feels both have what it takes to prosper in England and says patience will be key if they are to do so.

“They are in two different situations. It is Richarlison’s first time in Europe, he is a young boy and is a talent, I am sure about that and he can help us,” Silva said.

“He needs to make adaptations and learn a new language as well, but I think he can help.

“Kiko is different, he needs time to adapt to the competition. Playing at right-back in England is different to Spain. He is a boy who works hard and is ready if I need him.”

Femenia has shown glimpses of quality in attack, but was found wanting at times when fulfilling his defensive duties on Saturday.

Silva believes the former Alaves player will come good once he has adapted to the tough environment of the Premier League.

He said: “It is easy to understand [the differences]. It is hard competition, a more physical competition, and Kiko is not a tall player. He can help in the other situations if he is needed.”

Both are likely to be needed for the foreseeable future with Pereyra and Janmaat not expected back until after the September international break.

It could, Silva argues, be a blessing in disguise as he feels regular game time will be the quickest way to help both adapt to the demands of their new surroundings.

He said: “The Premier League is a different competition, but the football is the same all over the world.

“Of course, they need to understand and with the games they will understand fast. The best way to improve is in the match, sometimes play well, sometimes make mistakes, and this is the best way to improve.”
