"It's not a bad idea and a way at looking at things from Chelsea's perspective," Jagielka told the Daily Mirror.
"Unfortunately for Rom, with Chelsea mainly playing one up front, he had a big decision to make whether to stay there and play five or 10 games a season or do what he did when he went to West Brom last season.
"I think he made the right decision. That's already been proven and we're only a third the way through the season.
"If he helps us perform against the so-called big boys and rivals of Chelsea, then it will be a very good decision by them.
"Rom has played a massive role with his goals, but also his presence on a day-to-day basis lifts everyone.
"He's hard work to train against, though. I try to stay as far as way as possible.
"We don't do too much contact stuff, but when we do it is difficult - as it is playing against any of our attacking players.
"I try to use my brain a little bit and choose him on my team or make him go on the left of the forwards. It makes my life a bit easier."
