Why will it be messy?

Although Derek Jeter is coming off a year with career lows in batting average, slugging percentage and on-base percentage, the N.Y. Yankees need to compensate him accordingly. The N.Y. Yankees have already stated that the Derek Jeter negotiations may become messy. Why is that? Derek Jeter means so much more that numbers to the Yankee organization as well as the fans all around the world. Jeter is a global icon who is on the verge of 3000 hits and he shouldn't reach this milestone in any other uniform other than the pinstripes.
