Marco Silva is not surprised about the growing interest in Richarlison following the Brazilian's promising start to his Watford career.

The 20-year-old, who arrived at the club from Fluminense for £13million shortly after Silva's appointment as manager in August, is a reported transfer target for Tottenham.

In 12 appearances so far he has scored four goals as part of a new-look team in which the long-serving Troy Deeney has become peripheral, and asked of the attention he is attracting, Silva responded: "It's not a surprise if these clubs come to see him.

"It's not really a surprise. He's had a fantastic impact at our club and on the Premier League. It's a normal situation that everyone's starting to talk about him, but most important is that he keeps going, to improve.

"He's a player with a lot of quality so it's normal if everybody starts to pay attention to him.

"He's a different type to the normal Brazilian player; for what we wanted for our team he's the player with the (right) skills.

"We are talking about a fantastic talent, a very, very good player. I'm sure in the future he'll achieve everything he can."

Silva, 40, was also asked about Richarlison's chances of earning senior international recognition with Brazil, who over the past 12 months have reestablished themselves among the world's leading teams He said: "He went through all the youth levels for his national team and performed well.

"It's a fantastic national team, with fantastic players in the position he plays in, but it's a goal for him and I'm sure he'll work hard to achieve it.

"We analysed him for some weeks in June, when he was playing in Brazil. We took the decision to tell the board to do everything we could to sign the player."

Silva's team host West Ham in David Moyes' first fixture as the Hammers new manager this afternoon, and at a time when both high-intensity football is increasingly popular and the visitors are widely thought to have been underworked, the Hornets boss dismissed the contrast between the sides.

One set of statistics showed West Ham had made the fewest sprints in the division, with 4,942, and that Watford had made the second most with 5,950, but Silva - also boosted by the returns to fitness of Heurelho Gomes and Christian Kabasele - said: "It's not always the team who runs most that wins the game.

"We need to run well. I'm sure we ran more against Everton, but we didn't win. I'm sure we ran more in the game against Stoke, but we didn't win. Football isn't just about the team who runs more."
