This shouldn't have been a deal the Blues are suppose to be happy to get to be honest with you, I don't think Chelsea need any more players because they have all it takes to be stronger again, they get in players but yet to let go off some players is a problem. The Blues are acting like the 3 Lions of England, they want everything just to be winning trophies but is not working. The player they signed can't bench any player in the Chelsea squad that is playing same position as him, highest is to send him on loan or the B team to play.
Chelsea have lots of players who haven't been in action since they signed for the club and that position (Attacking Midfield) is not even the problem of the club. To me I'd say get a good striker to get them goals because without lots of goals you're winning nothing, make Jackson competen for his position as a striker and sell some players like 2-3 players who haven't been active at the club, not getting more players to confuse the manager, signing teenagers who lack experience all in the name of building the team isn't the solution to their problem.
The season will soon begin because currently we don't know what the problem is with the Chelsea management, they are recruiting young players they like. I don't think Chelsea goal is to win trophies alone because they already have the players they need to win their games next season, I believe no team has sign more players than Chelsea since the end of this season games, they have had the best players, but they continue to add more players. I think Chelsea wants to be one of the best clubs in the world, they want to buy young players and develop them, If they improve and perform at a high level, they will be able to sell them at a high price, like Real Madrid, which has 15 Champions League titles, they bought players for low fees and developed their performance before selling them at high prices.
In addition, if Chelsea wants to build a team, they don't have to depend just on young players, however, they should strengthen their squad with experienced players to be serious with their performance. Chelsea did not have a striker last season, so they used Jackson. Though Jackson is not a bad player, he lost a lot of chances to score goals, if Chelsea had the best striker in the position, I believe he would convert the chances into goals. Chelsea needs to sign another striker since they did not agree to swap Lukaku with Osimehn.
From what you said about Chelsea do you think the owner have a clue of what he is doing? Let me remind you that without the fans the club is nothing and the management or should I say the owners of the club need to do something to make the fans happy because they are losing it, I mean the fans. You get more players and they play like amateur without any trophy or even competing for the title and also finishing outside the top 6 team on the log, you expect the fans to be calm and happy about it, no it can't happen.
They can't be like Madrid or even PSG, is best they solve the problem than recruiting players that won't add any value to the club. Jackson can never be a better player until he starts performing well and they have Broja but they sent him on loan which means they don't want the club to excel, with Lukaku still on the team I think he can make a difference only if he stays.
