a) Wisdom is terrible;
b) Yacob and Mulumbu were the best axis we've ever had in the history of our Premier League status. Play them together, we'll improve defensively, and can also justify playing Varela, Blanco and Sessegnon in front of them. That way you have 2 players specialised for defending and 3 for attacking. At the moment, we have 4 who do neither particularly effectively (Morrison, Gardner, Dorrans, Brunt);
c) Attack is the best form of defence. The more possession we have in the oppositions half, the less time they have to hurt us.
