David Moyes has become the new manager of Everton after signing a four-year deal at Goodison Park. The 38-year-old Scot, who moves from Preston North End, believes he can keep the Premiership strugglers up.
He said: "I don't think you get jobs in management when they are easy. I have great faith in what can be achieved here. I'm under no illusions.
"I would be lying if I said it wasn't a big job. It's been a big job for all the previous managers here.
"I would prefer not to be in this situation, I would prefer to be at the top of the league."
Everton, who are languishing near the bottom of the Premiership, only sacked Walter Smith on Tuesday night.
But they have moved quickly for Moyes, considered one of the brightest young managers in football. Everton have nine games left for Moyes to turn around their poor season.
The Merseyside club have agreed an initial £1m compensation to Preston, because Moyes was only one year into a five-year deal with the Lancashire club.
If Moyes keeps the Toffees up a further amount will be payable. Moyes' first game in charge will be against Fulham at home on Saturday.
Preston chief executive Tony Scholes said Kelham O'Hanlon and Jimmy Lumsden would take charge of Preston for their match against arch-rivals Burnley.
Scholes said: "Whilst our preference would have been for David to remain as our manager, it would not have been right to have stood in his way once he made it clear he wanted to go to Everton.
"We have reached a very good settlement and I am glad that we reached an amicable solution in a civilised manner."
Former Everton player Tony Cottee told BBC Radio Five Live: "I am pleased it has all been done so quickly.
"Only time will tell but I hope he is a success and keeps Everton in the Premiership. I hope he will give them an injection of confidence. They have got to beat Fulham on Saturday."
