New stadia, a slip for City & advantage Arsenal in Europe

Ellen, Jen and Ben digest a huge week, which saw WSL leaders Man City drop points and put Arsenal 90 minutes from the Champions League final.
With Arsenal taking a 2-1 lead into the semi-final second leg; how were they able to handle Lyon? And can they keep it up?
In the other semi, it's level between Bayern Munich and Barcelona where Franziska Kett was sent off for a hair-pull; are we seeing more of that as an offence?
As for the WSL, Manchester City remain in the driving seat for the title, but how costly might Saturday's loss to Brighton prove to be? 
And as Chelsea make a permanent move to Stamford Bridge and Brighton announce a new purpose-built stadium, how do clubs ensure that these projects work? And what do Ellen and Jen want to see as part of the plans?
