#4 Danilo Pereira (Porto to PSG)
Portugal international Danilo Pereira has sealed a loan move to Paris Saint-Germain from Porto after impressing last season.
He is a goal-scoring defensive midfielder who found the net 19 times last season for Porto while also getting eight assists. PSG have the provision to buy him permanently next summer and it remains to be seen if the Parisian giants exercise the option to do so.
#3 Facundo Pellistri (Penarol to Manchester United)
Manchester United pursued Jadon Sancho throughout the transfer window, but baulked at his asking price. Instead, the beleaguered club went for youth in their pursuit of a wide player.
The 18-year-old right-winger has been scouted by United for some time and is one of the brightest prospects to emerge from Uruguay in years.
#2 Moise Kean (Everton to PSG)
Moise Kean is only 20 but already has top-level experience in the Premier League as well as the Italian top-flight. Though he only found the net four times in 37 appearances for Everton, Kean is one for the future and PSG, who will continue their pursuit of the UCL this season, have picked him up on a loan deal.
Kean has already won the Serie A with Juventus and has also appeared in the Champions League for them. He is also an Italy international who could still become a key player for club and country in the coming years.
#1 Douglas Costa (Juventus to Bayern Munich)
Brazilian winger Douglas Costa has heaps of experience and returns to familiar territory, rejoining Bayern Munich on loan from another European giant, Juventus. The move makes sense for both clubs, with Pirlo's side having many attackers and Bayern needing reinforcements in wide areas after Ivan Perisic returned to Inter Milan following the expiry of his loan deal.
Costa impressed when he was fit in Turin, but injuries blighted his time in Italy. He will be looking to rediscover his mojo at Munich for the treble winners.
