A domino effect (or chain reaction) – the cumulative effect produced when one event sets off a chain of similar events.That’s the definition of what Paris Saint-Germain started a few weeks ago by signing Lionel Messi from Barcelona. It caused a series of events on the transfer market that will thoroughly change the surface of European football. It’s finally official: Lionel Messi signs a two year contract with PSGMaybe the most important consequence of Messi’s arrival to Parc des Princes is Kylian Mbappe’s ego issue, which urged him to decide to leave Paris instantly. His departure (and a one-way ticket to Madrid) will allow Mauricio Pochettino to bring a replacement, but you won’t find too many (if any) forwards on the market capable of reaching Mbappe’s ludicrously high levels.Paris Saint-Germain send a clear message to Real Madrid: Either pay what Mbappe is worth or go awayAnd Everton’s poacher Richarlison is definitely not the one you’ll expect to deliver out-of-this-world performances. However, as if from today – he’s PSG top target.His agent Giuliano Bertolucci arrived in Paris for negotiations with Nasser Al-Khelaifi.Neymar is also a serious factor in the whole story since he is a great friend of Richarlison. Together, they played dozens of matches for Brazil, for which the former Fluminense player made his debut in September 2018, a month and a half after Everton bought him from Watford for 39,200,000 euros. Since his debut, Richarlison has recorded 32 appearances and ten goals and five assists for Brazil, with whom he won the Copa America in 2019 and the Tokyo Olympics.Richarlison and Neymar (©MB Media/Getty Images)Still, he didn’t thrill at Everton. From time to time, there were awe-inspiring performances, but also reckless moves, red cards. His potential is unquestionable, but 43 goals and ten assists in 121 appearances show he has not yet made the final step forward.PSG tryna replace Mbappe with Richarlison pic.twitter.com/RdwqnBWSPC— Dém (@TyIanWaIIace) August 27, 2021 Ever since the Fluminense jersey, he has been considered a guy who does not make his teammates better but gets better with better teammates. And where will you find better quality than Neymar on the one end and Lionel Messi on the other, as well as Angel Di Maria coming from behind? With the departure of Mbappe, which is a condition for his arrival, here is his chance to impose himself next to Mauro Icardi as the first attacker.NANTES – OLYMPIQUE LYON
