If Chelsea buy two big-name strikers, as the media insists they're going to, it would suggest Jose doesn't think Lukaku is ready for CL football. In that scenario, I can actually see them loaning him to us again.
1) We aren't going to be competing for the Prem title (yet..... 2015/16 however, we might)
2) We aren't going to affect Chelsea's CL campaign
3) We aren't one of their hated London rival clubs
4) We can offer Europa League experience for the kid
5) We've shown this year that we can nobble Arsenal, stopping them from catching Chelsea. You know Jose loves the taste of popcorn.
It's actually a decent means for Chelsea to let him develop - and if he flops in the EL, then they'll have lost nothing.
If we can loan him for another season it will make a MASSIVE difference to our summer spending plans. Imagine this:
Barry - free transfer
Deulofeu - another season loan
Lukaku - another season loan
Lescott - free transfer
Diame - £3.5m
Even with loan fees and signing-on fees, that lot would cost less than £10m. Ok the wage budget might squeal.....
