Michael Bell feels Allied Powers could go very close in a Group One contest if he got suitable underfoot conditions.
The five-year-old is a winner at Group Two and Group Three level when there has been plenty of cut in the ground, but has yet to hit the target at the highest standard in two attempts.
However, he was far from disgraced when only beaten a length and a quarter in fifth place behind Campanologist in a Group One at Hamburg on Saturday.
"He was only beaten just over a length on ground that was plenty lively enough for him," said the Newmarket trainer.
"We were delighted and he'll be in the mix in a Group One when he gets conditions in his favour."
Bell has still to make a plan for Wigmore Hall following his narrow success in the John Smith's Cup at York earlier this month.
"I'm not quite sure where he's going yet. There are one or two irons in the fire, but I need to sit down and have a chat with the owner as to how ambitious we are going to be," Bell went on.
"There are one or two options abroad and the like. We'll try to win another nice prize with him somewhere along the line if we can."
