How can we prepare for Europa League?

I think almost everyone will agree that it's unlikely that we'll finish in the top 4 now after yesterdays result against Spurs. If we do miss out on top 4 then that would leave us in the Europa League and miss out on top 4.

I read somewhere that if we don't get top 4 then we'll miss out on a lot of money from CL, so therefore, in order to make that money back we will have for sell naming rights for our ground if we want to spend big that will be the only solution. I'm not quite sure, so can someone confirm this for me please?. If we miss out on top 4, do we need to sell stadium naming rights in order to spend big?.

If we do play Europa League for a season, I wouldn't be bad as I thought it would be if the above problem can be resolved, this is because we are a club in transition so therefore, we will continue rebuilding by getting rid of the old guard and replacing them with fresher legs who are hungry for success. Also Spurs played their youngsters in the Europa League this season and got the main players to focus on top 4 and it looks like the plan worked. We can do the same, another positive would be we wouldn't have to loan out players like Mceachran, Luaku, De Bruyne, Kakuta, etc simply because we can have these kind of players gaining vital first team experience in the Europa League which will be really good because they'll be gaining european experience in the future also, they'll be playing in the Carling Cup and maybe FA Cup as well and if they are successful maybe given a chance in the first team in the league. In the Premier League we can play our strongest team and push for top 4 or maybe winning the Premier League but top 4 obviously our minimum target.

-Should we keep hold of players like Mceachran, Lukaku, De Bruyne, etc and play them in Europa League for them to gain experience or take the tournament seriously and loan them out?.
