There are rumors that Chelsea are interested in signing Inter Milan centre-forward Lukaku, a Belgian who used to be unsuccessful at Stamford Bridge, who played at intermourse, but Chelsea's signings in Serie A in the past few seasons have been mixed.
<h1 class="pgc-h-arrow-right" data-track="2" > Quadrado</h1>
When Mourinho coached Chelsea for the second time, he has always been troubled by the right wing, whether it is Andre Schuler or Willian, the performance is obviously different from the left-wing Hazard. So in January 2015, Chelsea brought Cuadrado to Mourinho for £23.3 million, hoping he could fly with Eden Hazard on both wings. But the Colombian unexpectedly did not gain Mourinho's trust, playing 14 games for the team in half a season, mostly as a substitute; in the summer, he was abandoned by Mourinho, loaned to Juventus, and then bought out by Juventus for 25 million euros.
<h1 class="pgc-h-arrow-right" data-track="4" > Marcos Alonso</h1>
Marcos Alonso was Conte's focus after "getting on the train" for a transfer fee of £24 million. The Spaniard, who played for Fiorentina, was notoriously an ordinary full-back, but the Blues were greeted. In a 3-4-3 formation, Marcos Alonso became the Blues' left side king, scoring 24 goals for the team in five seasons, making him the most goal-scoring Premier League defender in recent years. However, after Conte's departure, the team switched to a four-back defensive formation, and Marcos Alonso's weakness of slow speed was also exposed, and he could never play back to the high level of the 2016-18 season.
<h1 class="pgc-h-arrow-right" data-track="6" > Emerson, David Zapa costa, Antonio Rudiger</h1>
In the following season, the Blues "knew the marrow" in Marcos Alonso's transfer, introducing three Serie A defenders in succession, namely left-back Emerson, right-back David Zapa Costa and centre-back Antonio Rudiger. But of the three, only Antonio Rudiger can make a foothold at Chelsea. Emerson and David Zapa Costa have transfer fees of 20 million euros and 28 million euros respectively, and Chelsea's two transfer fees should be thrown into the sea. However, Antonio Rudiger has been very stable in the team's four years, under the four coaches are the main center-backs, playing 149 games for the Blues, and is an absolute contributor to the team's victory over the Europa League and the Champions League.
<h1 class="pgc-h-arrow-right" data-track="8" > Jorginho and Higuain</h1>
After Sarri took office, the team also brought in two older players from Napoli, midfielder Jorginho and centre-forward Higuain (Higuain was borrowed by Juventus in the middle of the season). Jorginho's first season at Chelsea was dismal, with thousands of passes failing to collect a single assist, and his performance has improved over the past two seasons, with only four assists in 141 games for the Blues as an organised midfielder. The Italian has finally gained a foothold under Thomas Tuchel, but there is still much to be done. Higuain only had half a season because the time was so short that it was a bit of an understatement to say he was a failed acquisition, but overall his performance was mediocre and he was not retained by Chelsea after Sarri left.
