Posh’s time in the Championship came to an end on Saturday (April 23) with defeat at home to Nottingham Forest.
McCann lifted the League One title the last time he managed in the division with Hull and his thoughts will now turn to repeating the feat with Posh.
To do this, he has said he expects between 75 and 80% of the squad to stay and has meetings with the club’s hierarchy this week to discuss transfer strategy.
Speaking after the relegation, he said: “We have got 75/80% of the squad staying for next season, which is great. I think we need to add a little bit of knowhow to the group, bits of leadership and people who know the division and then I think we can have a really successful season next year.
“I have already got some ideas in mind, we have been working all the time. I’ve got meetings this week with the owners and the plan will be put in place.”
McCann also confirmed that he will be treating the final two games of the season, away at Millwall and home against Blackpool, as business of usual. He may be without Ricky-Jade Jones though. The forward was withdrawn at half-time complaining of a back injury
