CRAIG MACKAIL-SMITH says Peterborough will come first as he aims to sign off after five seasons at London Road by helping Posh win promotion at Town’s expense.

The 27-year-old Scotland international is set to leave the club this summer, with Premier League-bound pair QPR and Norwich said to be among those interested.

That means Sunday’s Old Trafford showdown will be his 205th and final appearance for the club he joined from Dagenham and Redbridge in 2007, and for whom he has netted 98 times.

Mackail-Smith, who bagged his 34th goal of this season as Posh overturned a 3-2 first-leg deficit by beating MK Dons 2-0 in the semi-finals, has twice won promotion previously.

He helped Posh go up from League II in 2009 and League I the year after, and now he’s desperate for a hat trick.

“It would be absolutely brilliant to finish off with a win at Old Trafford,” he said. “But I don’t really care who scores the goals as long as we get to the Championship.

“Regardless of what happens at the end of the season, the main thing is it to make sure I help us get promoted.

“If the semi-final on Thursday night is to be my last game at London Road it will live long in the memory. They were great scenes and hopefully we can enjoy plenty more of them at Old Trafford.”

Watford-born, Mackail-Smith played for non-league sides St Albans City and Arlesey Town before joining Dagenham when they were in the Conference.

Previously capped by England at semi-professional level, he qualifies for Scotland through his grandmother and made his debut against Brazil at the Emirates Stadium in March.

DARREN FERGUSON says his Peterborough side will be ready to stand up for themselves on Sunday.

The Posh boss said: “Huddersfield are on a fantastic run and were unlucky not to go up automatically.

“It will be a different game to the semi-final. They are a more physical side than MK Dons, but we will be ready for them.

“When we are on our game we are very, very hard team to beat and a match for anyone.”
