I know nothing of Sugawara other than statistically on paper but this seems to tick some boxes as a replacement for KWP. Good age, playing regularly in the Eredivisie, fairly tall, has a handful of goals and assists, Japanese International (and we have a pretty good success rate amongst the Japanese players we've had). The alternative appears to be Aarons who is decent going forward but shorter and defensively questionable. Unless the idea is to bring both in and ship out Bree.
Oh, and if the Ox buys his contract out and is available on a free, I'd be happy with him. The questions are over his injury history not his talent and for a free transfer it's worth a punt. He's only 30 too which surprised me.
