I don't know, why would he be a bad option? Lets face it, Barcelona spending a ton of money on Lewandowski like it has been talked about would be a financial trouble for them and I would advice otherwise. If they could get Suarez for nearly a free amount, they could make him play plenty of games for sure. They already have aubameyang at striker position, along with him and Suarez they would be pretty good if you ask me. I know that it is not a clear situation, and I know that it will take a while before they could get out of debt, but when they are in debt, its better to get Suarez for cheap instead of spending money for a better player. Why waste resources when you can get a cheap player that could bring in "enough". Yes Lewa would be a lot better, but he would also ruin their finances even deeper and that makes no sense.
Now after having the worst last season they are doing their best for having good current season so just because of this they are investing big amounts on their desired players. Few days back I read they already sell their media rights which are giving them 700 million which is big amount and this can settle their few financial issues as well.
Robert Lewandowski is their target for some time and now most chances we will have this good news in next few years because Bayern Munich can sell him for targeted price of 50 million and just because of this they are creating some feud with they already have Sadio Mane who can replace him, and they can achieve their required results from their new transfer.
Barcelona having Auba but with this signing they can break any defense in La Liga and Champions League which they're targets for this season and settle their financial issues.
