Valencia have signed Portugal winger Goncalo Guedes on a season-long loan from Paris Saint-Germain.
The two sides reached an agreement last week, but Valencia had to wait until PSG signed Monaco star Kylian Mbappe before the deal could be completed.
Mbappe joined PSG on Thursday evening, thus paving the way for Guedes' departure on Friday.
Valencia, who have loaned former Manchester United winger Nani to Lazio, were keen to strengthen their attack before the transfer deadline.
Guedes, 20, played just once for PSG in Ligue 1 following his €30m move from Benfica in January 2017.
Valencia drew 2-2 to defending La Liga champions Real Madrid last weekend and are unbeaten so far this season.
Coached by Marcelino, Valencia resume their campaign after the international break with a home game against Atletico Madrid on Sept. 9.
