Re: homegrown limits, the signing doesn't seem to change much:
17 non-homegrown (which = the maximum for League & CL):
Čech, Schwarzer, Hilário, Ivanović, Luiz, Azpilicueta, Essien, Ramires, Mikel, Mata, Oscar, Schürrle, De Bruyne, Hazard, Willian, Ba, Torres
1 club trained:
Terry
5 FA trained:
Cahill, Cole, Lampard, Bertrand, Moses.
u-21:
Van Ginkel, Lukaku
So they'll be fine when it comes to the Premier League unless they want to add another non-homegrown player, & assuming Moses misses out when it comes to the CL squad, if they want to add Rooney (without losing a non-homegrown player), Bertrand would likely have to miss out too.
