Chelsea will return home to face Atletico madrid in La Liga in the second leg of the Champions League in Mid-March, and the two teams have met from time to time in Recent Years in Europe, which can be said to be old rivals. Chelsea and Atletico have a lot in common, both teams started with defensive counterattacks, building their own dynasties and hegemons. In recent years, many players of the two teams have exchanged owners, and this article will be detailed. (Because there are a lot of players who have played in both armies, such as some that are not directly transferred by two teams, such as Falcao will not talk about it)
<h1>Thibaut Courtois</h1>
As early as 2011, Thibault Thibault moved to Chelsea, but instead of getting a chance at the Blues, he was immediately loaned to Atletico for two years. In the first two seasons of Atletico, Thibo Courtois took over the position of atletico's goalkeeper from the vacancy left by David De Gea and has been contributing to a steady performance; in the summer of 2013, Atletico applied to extend his loan contract for an additional year. As a result, Atletico and Chelsea met in the final four of the Champions League that year, and with Thibault Courtois's wonderful performance, Atletico successfully eliminated the Blues into the Champions League final. In the following season, he was taken back by the Blues and became a hero in the Premier League in the 14-15 and 16-17 seasons. But in the summer of 2018, he threatened to transfer to Real Madrid in the form of a strike, and the two sides broke up; many Chelsea fans regarded the Belgian goalkeeper as the "most anti-bone" player in modern times.
<h1>Filipe Luis, Diego Costa</h1>
In the summer of 2014, Mourinho signed two Atletico Brazilians in one fell swoop, left-back Felipe Luiz and centre-forward Diego Costa. The two had different encounters with the Blues, with Philip Luiz not being valued by Mourinho and returning to Atletico after one season, while Diego Costa shined at the Blues, having been a major player in the Blues' strikers in their first three seasons, scoring 52 league goals. Unfortunately, he eventually fell out with Conte and returned to Atletico in the summer of 2017 following in the footsteps of Philippe Luiz.
<h1>Alvaro Morata</h1>
In fact, Alvaro Morata trained in the Atletico academy before joining the Real Madrid academy system. In the summer of 2017, he moved to Chelsea for around £60 million, but his performance in the first half of the season was not as expected, and Sarri Yinin borrowed Higuain more than reused the Spanish striker. In January 2019, Atletico borrowed back the former academy for £10 million, and in the summer launched his £58m severance clause to sign him. In his two years at Atletico, he scored 18 goals in 49 games, but left the team after a season and a half, and he has now been loaned to Juventus in Serie A.
