“The Premier League is the best league in the world and just to test myself in it each week is a dream come true and it makes me better because I have to improve more, be switched on more, learn more.
“It's an amazing opportunity to have and an opportunity we want to thrive in.
“We're a team which tries to contain teams. We must defend well, if we get a chance then you have to be clinical.
“If you get in a position then finish it off and defend as a unit, defend for our lives."
