In the 17th round of the Premier League, Chelsea played at home to Everton, as one of the backward teams in the Premier League title, Chelsea can only hope to continue to maintain the situation of the top three in this game if they strive to win. However, in this game, Chelsea had an absolute advantage in the whole game, still failed to get 3 points on Everton, and the opponent's goal in the 74th minute made Chelsea's efforts disappear, and it could only regret that it ended with 1 point. After the match, Chelsea had just 37 points in the table, already three points behind second-placed Liverpool and four points behind Manchester City at the top of the table.

In this game, many players in the Chelsea squad were absent due to the epidemic, including the team's two centre-forwards, Lukaku and Werner, and Tuchel had to arrange for Pulisic to be the team's starting center. From the game's data, Chelsea occupied 80% of the possession of the whole game, and the number of shots on goal was as high as 23 times, 10 shots on target, but in the face of the 5-guard system, Everton still did not have a good way. Judging from this game, the wolf tactics are very useful, but they still need a siege hammer when facing tough defense.
In the absence of Lukaku and Werner, Chelsea let Pulisic, who has not played much this season, play the starting center, which is more of a helpless choice, the 23-year-old young shooter is not suitable to be the fulcrum of the team, more suitable as a sharp knife, in this kind of game of disparity in possession, Pulisic's space is actually very limited. It's not that Tuchel doesn't understand this, it's that he has too few candidates at his disposal, and with the exception of the two starting centers, the team's injured squad is already overcrowded, and no matter how thick the depth of the squad is, it can't withstand such a toss.
After the game, some fans attributed the team's defeat to two points, one was that Lukaku failed to show the strength of a billion-dollar center this season, and the other was that Tuchel failed to show the tactical adjustments needed by a Champions League-level manager. However, many overlooked the huge changes Tuchel brought to the Chelsea after taking over from Lampard last season and the adjustments he made to the team in Romelu Lukaku's absence. It is not that Tuchel does not have the strength, but that it is difficult for a woman to cook without rice, and the space that can be adjusted in her hands is actually limited.
As for Lukaku's problem, the Belgian monster has only been amazed by a few games since joining Chelsea, but it must be said that Lukaku has not yet found a position at Chelsea, which is related to his own technical characteristics, but also related to the team's squad and Tuchel's personnel arrangement. But it cannot be denied that Lukaku's ability is not too much of a problem, but more of how to use him. Lukaku needs to adapt, Chelsea needs to adapt and Tuchel needs to adapt.
