“I didn't know what it was going to be like when he came," said the Nigeria midfielder.
“I can't lie, it was a bit weird [at first] because I grew into the system playing under Arsene Wenger and that is all I have known.
“But when he did come — I came late to pre-season as I was at the World Cup — he spoke to me and said what ideas he had for me.
"I have bought into them and I've played in a lot of matches and he has shown a lot of faith in me. I thank him for that.
“Especially at a young age, to be involved in as many games makes me proud, but I have still got a long way to go and I am sure he has a lot more years at the club as well.
“You can see everyone is fighting, not just for us, but for him. He has a good chemistry with the players and you can see that in his time here.
“To get us to a final, he has had the right tactics and the right players at the right time. We will do our best to win the final for him as well."
