Fulham have completed a triple loan move to land Manchester United defender Timothy Fosu-Mensah, Sevilla goalkeeper Sergio Rico and Atletico Madrid striker Luciano Vietto on transfer deadline day.
In addition to the loans, Fulham capped off their busy deadline day with permanent moves for 22-year-old midfielder Andre-Frank Zambo Anguissa from Marseille in a reported £22.3 million deal, and for left-back Joe Bryan from Bristol City in a deal reportedly worth about £6 million.
Fosu-Mensah, 20, signed a season-long loan deal at Craven Cottage after spending the last campaign at Crystal Palace. Newly promoted Fulham beat competition from Bundesliga side Hertha Berlin for his services, sources told ESPN FC.
The Netherlands international, who has made 21 senior appearances for United since his debut under Louis van Gaal in 2016, played 24 games for Palace last season.
"A good loan is a loan to play," Mourinho told MUTV on Thursday morning. "They just have to play -- it doesn't matter if that team plays to be promoted, plays to not be relegated, plays in England, plays outside England -- they have to play and that's the most important thing, because for playing bits, playing minutes, to be on the bench, to be a squad player, they can be here."
Rico, 24, won the Europa League twice with Sevilla and made over La Liga 100 starts for the Spanish club.
Fulham have already signed goalkeeper Fabricio from Besiktas, but the 24-year-old Rico will arguably have the inside track on being their No. 1 this season.
"I'm very happy, really pleased to have signed for the oldest club in the Premier League," Rico told the club website. "I'm excited to start training, to meet all my teammates and, above all, to enjoy the season that starts this Saturday."
Argentine striker Vietto, also 24, has struggled at Atletico since his €20 million move from Villarreal in 2015, scoring just one La Liga goal in 25 games with similarly disappointing spells loan at Sevilla (six goals in 21 league games) and Valencia (two in 14).
He did manage a hat trick against Las Palmas in the Copa del Rey in January, and now will be seeking more consistent form as he moves to London.
"Luciano is a versatile young attacking player, and he has already gained great experience against elite competition in La Liga," director Tony Khan said.
