Chelsea does have quite a lot of defenders if we look at the list of players Chelsea have, but there are not many that can be relied on now.
For center back only Thiago Silva and Kalidou Koulibaly who I think can make a good contribution, while the rest are young people whose
appearance is less consistent. While Azpilicueta and Alonso are still in the process of negotiating with Barcelona, if the two players move,
Chelsea must immediately find a replacement.
In conclusion, I think Chelsea at least need to bring in at least one centre-back and get ready to find replacements for Azpilicueta and Alonso.
Then for Lukaku's replacement, it must also be immediately found a replacement, because Raheem Sterling who was successfully acquired by Chelsea
was not good as a center forward. Actually Todd Boehly wanted to sign Ronaldo as a replacement for Lukaku, but it seems Tuchel turned it down,
so Chelsea really have to look for other striker alternatives. I think Chelsea should have bought Victor Osimhen to replace Lukaku, but there doesn't
seem to be any rumors linking Osimhen to Chelsea.
