Preston have agreed a compensation package with Everton for the release of Toffees assistant manager Alan Irvine. The 49-year-old Scot will be unveiled as North End's new manager at a press conference later today after signing a three-and-a-half year deal at Deepdale to replace Paul Simpson, who was sacked last week. Preston chairman Derek Shaw said: £We are very pleased that Alan will be joining us, he's ready to have a crack at management. 'He's got a reputation of being a top notch coach, his work ethic is amazing, he's worked with (Everton boss) David Moyes and I know the amount of games they take in, you see them all over the country. 'David Moyes and Alan Irvine have set high standards at Everton and I'm pretty sure that Alan will continue to maintain those high standards at Deepdale.'
