The problem is exactly that they don't have a scoring forward. You can create a tiki-taka team and have different players scoring all the time so there is no dependence on a specific position, but it's hard to win that way because it's a very complicated strategy in general. So far don't see their transfers working out at all
Chelsea is competitive and dominated, the only thing they lack is having zero opportunities infront of goals. The frontlines don't know how to position, like Jackson doing what he does best, missing out on golden goal scoring opportunities, then we check Mudryk who's absolutely out of line wirh his uncontrollable speed, then the main striker Christopher Nkunku who's ruled out for a long time. Chelsea team is a mess and Mauricio Pochettino really needs to fixed the teams because there's alot of weaknesses of the blues that have been spotted out.
In my own analysis of Chelsea's current issues, I think the main problem in the team is that they lack a creative midfielder who'll be linking the attacking players and the defensive players. Mudryk before his arrival was a good creative midfielder who I thought will bring his creativity to the Chelsea midfield but we are yet to experience anything of such nature. He's been a shadow of himself and is now always left in the bench.
Mauricio Pochettino must find the best playing pattern that'll bring out the best in his players if he really wants to succeed at Chelsea.
