Nico Williams is younger than Lookman and he has two big advantages against Lookman: his experience in La Liga is what Lookman does not have and will need time for adaptation to a new league; and his understanding as well as good combination with Lamine Yamal in Spanish national team recent years. It is another disadvantage of Lookkman who will have to get familiarized with Yamal and build up bonds with other new teammates.
I believe transfer prices of Nico Williams and Lookman are not too different and both are expensive. However perhaps Nico Williams will cost Barcelona more money for his wage.
In my opinion, it is best if Barcelona will neither buy Nico Williams nor Lookman in order to focus on improving their club finance and resolve current debt gradually season by season.
The problem is that when Barcelona have Raphinha injured and Lewandowski also injured, Barcelona's attack becomes non-existent, even with Yamal on the field and they will lose a lot, and if the injuries are long-term, then Barcelona will not be able to achieve anything.
In my opinion, Barcelona should make a financial effort to sign Nico Williams and sign some other very skilled player capable of replacing Lewandowski, that way when Lewandowski and Raphinha are injured, the team will continue to be strong in attack and win games.
my view to bring in Nico certainly requires a large fund and indeed if bringing in Lookman certainly the cost is not as big as Nico. but yes if you see Nico who is already friends with Yamal and close of course that is indeed the advantage of Nico Williams but of course if you see this it would be better for Barcelona not to make both purchases to save costs but what is certain is that Barcelona's strength is threatened in Laliga next season.
I agree with you indeed if there is a key Barcelona player who is injured of course it will make Barcelona confused if for example Nico is not brought in and of course now Barcelona must try as hard as possible to be able to make their team strong and also have to improve their financial strength to the maximum. of course we'll just see what happens but honestly I personally want to see Nico Williams duet with Yamal again. but sometimes I also think if for example Nico leaves Bilbao, what do you think will happen ...
with Bilbao
