1 season back in the CL is your logical argument?
If you have any inkling about club finances, you'd know you need sustained CL qualification to compete financially with the other clubs that are making it in there every year, City Arsenal United Chelsea. 1 season doesn't cut it. What happened Spurs after their 1 season in there?
You also need sustained CL qualification to sign the top players, cos if you've not got that, you need to do a city wages wise to tempt players like Aguero Toure Silva and pay ridiculously over the odds, with no CL that's kind of hard with no sheik, RA and now with FFP
