Chelsea are doing great in the transfer market, they have brought in Raheem Sterling which comes as a upgrade to their attack with his pace and dribbling skills. Priotizing building their defense now is a solid move. Reportedly, a deal for Koulibaly is already agreed which is a smart move for Chelsea to replace Rudiger and a few more additions to their defense and a good striker and they are good to go.
On the other hand, Chelsea didn't lose either because Tottenham signed players sooner than we thought. The ambition to be in the top 4 is increasingly contested. In the Premier League which wants to win a Champions League seat, Chelsea will face many big obstacles from Tottenham. So signing Raheem Sterling is the same seriousness Chelsea is showing.
