#3 Paco Alcacer (FC Barcelona to Borussia Dortmund, Aug 2018)

Dortmund have a knack of signing great talents to replace their outgoing talents and they have done it again once again with Paco Alcacer. With Pierre-Emerick Aubameyang leaving for Arsenal in January, Dortmund had tried Michy Batshuayi on loan to a fairly successful extent. But with the summer loan signing of Paco Alcacer, they have hit the jackpot.
Paco Alcacer has been netting goals for fun with a league-high 11 goals in the Bundesliga. What makes Paco's transfer even more mind-boggling is the fact that he has scored a goal in every 40 minutes playing for Dortmund in the Bundesliga. A classic case of being in the right place at the right time, Alcacer has already scored dramatic goals against the likes of Atletico Madrid, Bayern Munich and a thirty minute, match-defining hat-trick against Augsburg. With Dortmund already exercising their option to sign the Spain International at the end of the season, Paco Alcacer and his goals would be critical to leading Dortmund to their first Bundesliga title since 2012.
