Everton added three new players before the English transfer window closed on Thursday.
The Toffees started off by signing Brazil forward Bernard from Shaktar Donetsk on a four-year contract.
"Everton is a club with a great structure and a lot of tradition, historically the fourth most successful club in England," he told the club's website.
"This is an ambitious club which is aiming to achieve real success with [manager] Marco Silva's ideas and the new players coming in."
Later, Barcelona announced it will sell Colombian defender Yerri Mina to Everton for 30.25 million euros (35 million dollars) plus 1.5 million in variables while also sending midfielder Andre Gomes to Goodison Park on a season-long loan.
West Ham's spending continued as Arsenal forward Lucas Perez and Fiorentina midfielder Carlos Sanchez became the eighth and ninth signings for new manager Manuel Pellegrini.
"I decided to come here because, first, it is the Premier League, second, it's a beautiful club and the fans are always helping the club and, third, for me it's an amazing opportunity and an amazing project the club are leading, being ambitious and keen to achieve good things," Sanchez, who played for Colombia at the World Cup, said.
In other moves, midfielder Mateo Kovacic moved to Chelsea on loan from Real Madrid as part of the deal which saw goalkeeper Thibaut Courtois join the European champions.
Leicester City signed two defenders - Dinamo Zagreb's Filip Benkovic and Freiburg's Caglar Soyuncu - and Wolverhampton Wanderers added Belgium midfielder Leander Dendoncker from Anderlecht in a loan deal that becomes permanent next season.
Newcastle signed Swansea defender Federico Fernandez, Fulham signed Bristol City defender Joe Bryan and took Sevilla goalkeeper Sergio Rico on loan and champions Manchester City added promising Australian teen Daniel Arzani from Melbourne City and will loan him out.
In other loan signings, forward Isaac Mbenza joins Huddersfield from Montpellier and midfielder Victor Camarasa goes to Cardiff City from Real Betis.
The English transfer deadline was brought forward to close the summer window prior to the start of the season this weekend.
Teams can not sign any more players but can still sell them abroad until the August 31 international deadline.
Though the window closed at 1600 GMT, teams have an extra two hours to complete any deal as long as the initial paperwork was submitted prior to the deadline.
