"The most important thing is to get the Olympiakos game played. Hopefully get through that competition. If we can it’ll be a massive lift for us.
"We know we’ve got ourselves in a poor position being 2-0 down and we’ve got to try and make it show and play well in the game."
"The biggest assurance is that they let me get on with the job. We make big plans for years going forward, that’s why they gave me a six-year contract. This club is not a club that works on short-term vision. It works on a long-term vision."
