MANCHESTER, England (AP) The final day of trading in Britain's summer transfer window began with Everton signing Argentine defender Ramiro Funes Mori and West Ham taking Cameroon midfielder Alex Song on loan from Barcelona for the second straight season.

Plenty more moves are expected, including Monaco forward Anthony Martial heading to Manchester United in a reported deal worth at least 36 million pounds ($55 million) that would make the 19-year-old Frenchman the most expensive teenager in the history of the game.

Funes Mori, one of River Plate's best players in the team that won the 2014 Copa Sudamericana and 2015 Copa Libertadores, moved to Everton for 9.5 million pounds ($14.5 million) on a five-year deal to provide competition for Phil Jagielka and John Stones at center back.

Funes Mori attended Everton's Premier League match against Manchester City last month, and was pictured wearing a blue-and-white Everton scarf, but had to wait more than a week before sealing his move.

''I feel happy because the people here have shown me a lot of love and I'm very happy and comfortable here already,'' said the 24-year-old defender, who was recently called up by Argentina for its upcoming international matches.

Song will be on loan at West Ham for the season, like last year.

''Everything was in a good place for me to come back here and I'm very happy to be here,'' said Song, whose children play in the West Ham academy. ''It's a pleasure and it's like I never left here. I'm still here and I'm happy.''

Premier League clubs have spent nearly 800 million pounds ($1.2 billion) in this window, which is close to breaking its record of 835 million pounds set last summer, according to football finance expert Deloitte.

''This level of spending continues to be driven in large part by the increases in domestic and overseas broadcast revenue in recent years,'' said Alex Thorpe, senior manager in Deloitte's Sports Business Group.
