The 22-year-old has not played since the Carling Cup tie at Scunthorpe last October after rupturing a cruciate knee ligament in training.
He is now on course to return to full training in the next couple of months and he is targeting a playing return, possibly by December.
"It will be great to play in a really good team. It's easy to forget that we were just a mid-table team not too long ago," he said.
"We had some decent players, in fact some very good players, but as a team we were doing average.
"Now when you see the way we played against Liverpool (a 3-0 win) - things are just looking so good.
"It would be so easy to play in this team. Having those sort of quality players around you makes it easier."
On his recovery progress Johnson told the club's website: "It's going well. I saw the surgeon two weeks ago and he said about six to eight weeks before full training.
"Getting full fitness from there is another step but December doesn't seem that far now, everything's getting a lot closer for me.
"I'm out there getting fit, and that seemed a long way off back in February.
"I'm not rushing it but a game before December would be a bonus, really."
