It's a fair comment Mizer, but I would argue that Vernon has done very well coming off the bench. From what I have seen (yes no-where near as much as others) Zola takes two defenders with him and roughs up the defenders. Monday was a prime example of this and he holds the ball allowing space to be created for others. Then enters Vernon who plays a completely different style of game, one which has paid off in a number of games. But without the two overlapping it may not work. Let's not forget, I know a lot of people wanted Vernon away, thank fuck no-one listened to them!
I trust McIness, he clearly likes what he sees in Zola and for that reason, I trust him. No-one can deny that whatever it is, it's working.
Now, away to Siberia you serf!
