Benzema is definitely very expensive. Unless Madrid want him out he will cost 60-70 mill or so. Lacazette is not superior to mandzukic or morata. I'd rather watch Madzukic have an injury free season and being more settled at Juve and have morata continuing in his development than try a player like lacazette who we dont know whether he is good enough or not.
Mandzukic is a good player with his particular pros BUT there are cons like speed which is an important attribute
If we had both I assume Lacazette would bench Mandzukic until mid season because:
1. He is a faster player which can provide some great counter attacking plays and with our defense it could prove to be crucial against top teams
2. He is a better finisher - look at his number of goals he scored in the last 2 seasons! I`m not saying Mandzukic is a poor finisher as we all know he is a good one but the difference between good and great is what make you european champion!
To say overall Lacazette is a better player would be wrong as Mandzukic has some qualities Lacazette do not possess but I wouldnt say Mandzukic is better either...
As for Morata - Morata is a better player than both of them but he still cant bench Mandzukic because he has yet to develop his menace finishing skills. He could still do it as he is very young and thats why he is worth that much!
My guess is if he had that great finishing skills in him already he would cost as much as Higuain is rated now
Lukaku for example is rated this high because of his physique and finishing skills - No one would argue that Morata is twice as talented as Lukaku in terms of other skills and attributes but they are still rated at around the same price because those 2 are very important attributes!
Cavani is not a substantial improvement over Mandzukic/morata. He is better but not enough to warrant spending that much on him at this age and he is not for sale anyway. You are right 50m wont buy us any proper quality now. We cant get Aguero, Griezman, any of the madrid or barca boys, Higuain, Lewandowski heck even Lukaku.
Aubemayang maybe
? (BVB wont sell anyway or he is off to city for more)
Cavani is way better than Mandzukic! He is probably better at everything! As for Morata - He is better than Morata as well but Morata does has the potential to surpass him if he finds a nose for goal!
The thing is Morata is way more talented than Mandzukic yet Mandzukic is the starter - You wouldnt pay 50M for Mandzukic but you might do it for Morata...
For immediate results there is no point denying Cavani is worth 50M and certainly justify splashing the cash
If you look long term there are doubts as you might want to work on Morata and get a great player for many years!
As for Aubemayang - He is a good player but he wont do here what he does at Dortmund!
He is a fast player who can finish but with the defense in Italy he might find it hard here
As for a move to England or Spain - Yes! he would tear them apart! but in Italy you need something more!
