Chelsea have been spending heavily on young players this summer and I think Marc Guiu is the one who most interests me. As is known, Marc Guiu is a product of Barcelona's La Masia academy and last season, if I'm not mistaken, he played several matches with the first team.
However, overall he is actually quite a promising player but indirectly it is also difficult for him to get a place in the first team so Barcelona let him be sold and Chelsea also want to redeem his clause which is quite cheap at 6 million euros. His position is attacker and it feels like if Enzo Maresca can develop his potential better then he could be a solution for Chelsea in attack. Marc Guiu also has a contract duration until 2029 and it is a long-term project for Chelsea for him.
Marc Guiu is still very young because Marc Guiu is just 18 years old and thus, I am also not sure whether Marc Guiu was previously included in Barcelona's main squad or not. Because anyway, I only get a note that Marc Guiu is only included in the Barcelona youth squad and not in the main squad. Therefore, I personally might not have high hopes for Marc Guiu, because basically the competition to get into the main squad is difficult. But indeed, considering it looks like Chelsea is also still short of forwards, then it might make Marc Guiu will get good playing minutes with Chelsea later.
But yes, because he is still young and still does not have much experience to play in the main squad, then maybe Marc Guiu will also need time to be able to show his quality later. But right, the fact that Chelsea seems to be very focused on young players, and of course it will be good for the long term but with a note, Chelsea must be able to give confidence to the coach and not have to fire the coach too often.
