James believes that the side – who have gone straight from League One to the play offs for the Premiership – are a good example for the Swans to follow but also warns of not falling into the trap that befell Scunthorpe – last season's League One winners have made an immediate return back to the division.
Speaking in his column in the Evening Post, the former Welsh international said "They stormed through League One and were very convincing winners, but look at them now. Second from bottom in the Championship, their relegation is not surprising.
Scunthorpe have a small ground, small support and didn't bring in many new signings. They suffered the consequences from it and have taken a step back.
Swansea can't afford to do this and I expect Roberto to bring in around five new faces during the summer.
If he can pull a few more rabbits out of the hat and sign quality unknown players like he has already, then that's great.
It would be great to see the likes of young Welsh talent in Joe Allen, Shaun MacDonald and Chris Jones given a chance to grow next season, but if Roberto has to bring in quality from around the continent then so be it.
Bristol City have brought in quality players, along with a certain million pound man in Lee Trundle, and they can look forward to the play-offs.
Fast forward 12 months, Swansea would certainly take that."
James also advocates the signing of Welsh international striker Freddie Eastwood "see him playing alongside Jason Scotland – they would get certainly get goals in the Championship.
Obviously, that would depend on his availability, the transfer fee and discussions between Mick McCarthy and Roberto."
