(SPEEDWAY 1)DANISH star Kenneth Bjerre admits he faces a difficult decision between two clubs before determining his Elite League future in 2012.The Peterborough asset had spent several seasons at the Showground but the events of last winter saw him join local rivals King's Lynn on loan, where he again recorded a high average.Bjerre said: "Before the season, I didn't want to leave Peterborough. I had been there for years and it was a bit like home for me."King's Lynn feels like home for me as well, so I've got two places that I really enjoy, so it's going to be a tough call. I don't know yet what I'm going to do - it's 50/50."(SPEEDWAY 2)SHEFFIELD promoter Neil Machin says the club will start team planning for 2012 with a blank sheet of paper - after some high-profile departures.The Tigers finished runners-up in the Premier League but of their three heat-leaders Shane Parker has retired, Josh Auty has announced he is to race elsewhere next year and skipper Ricky Ashworth is yet to confirm his future plans.Machin said: "We have started to look at permutations but we haven't decided which way to go yet, either with a strong top end or with solidity throughout the team."Of course, the riders who are left from last season will come into consideration and we will sit down and talk to them, but at the moment we are a long way from being able to start naming riders."
