I'm not surpriosed he wants out of this league. Its a joke shop at this stage. SPL is a bigger league, more exposure, more money, better grounds (though possibly not a hugely better caliber of player in the main). Most importantly the club is in good shape. Massively better shape than the state Dunfermline were in when Kenny joined them. The fact that they are not a basket case and challenging for a european spot would be major attractions to Fenlon.
He has done everything he needs to do here and he has been outspoken many times about the shambolic way the league is run. With his sucess he is going to be linked with jobs across the water. A massive loss to Bohs if he goes but a opportunity he definately could not refuse IF he is offered. Therefore I believe he will take it if the position is offered to him. However it seems to be far from clear cut the more reports you read.
Re a previous post about his loyalty to the club. If he stayed with Bohs and delivered another league title, I dont think many bohs fans woud give a curse he was applying for/linked with other positions during the season. Just like it hasnt bothered them to date. He has shown his loyalty by winning 2 titles and getting the best out of his side consistently. Thats what counts. Sucessful people will always be in demand. Good luck to him.
