ENGLAND (REUTERS) - Everton manager Ronald Koeman says their new signing Wayne Rooney has already made a huge impact on the squad and believes the England captain's experience could lead the Merseyside club to a new level.

Rooney, who is the record scorer for the national team, returned to his first club after 13 years with Manchester United and was Koeman's sixth signing in the current transfer window.

"He has a lot of experience," Koeman told the official club website.

"He is an important player on the pitch, but also important for his team-mates and certainly the young players to show them what you need to do to reach that high standard of football.

"That means he needs to be a leader off the pitch and if I see how he's working and what he's doing with all the players, it's really what we want."

The Merseyside club have been one of the most active Premier League clubs in the transfer window, with their major signings including Rooney, Jordan Pickford, Michael Keane, Davy Klaassen, Henry Onyekuru, Sandro Ramirez and Cuco Martina.

With Koeman hoping to sustain a challenge in both the Premier League and Europa League during the upcoming season, the Dutchman believes they have added plenty of quality to the squad.

"I'm really happy with how the new players have settled in," Koeman added.

"They have great futures at Everton and provide the quality we need to improve."

Everton will begin their new season against Ruzomberok of Slovakia in the Europa League third qualifying round.

Koeman's side will be at home in the first leg on Thursday with the return fixture scheduled on Aug 3.
