(Through the week we’ll look at three Major League Soccer clubs per day, considering what they need to accomplish and what questions deserve answers during preseason training camps. Opening day in MLS is March 2.)

In terms of a lengthy preseason “to do” list, no team in the East has a longer one.

There really are more than three questions here. But the ones below are a starting point.

Once he arrives, new manager Ryan Nelsen will begin to build a back line that was pretty awful in 2012, make some order of a shapeless midfield and then line up some forwards amid ongoing personnel flux.

I mean, otherwise, things should be pretty smooth as TFC goes through another month and change of drills.

If we leave our biggest questions of philosophy and formations aside, here are some of the questions the club must answer during preseason:

How quickly can Nelsen catch up?

Yes, it’s totally bass-ackwards, players reporting and working out – and then welcoming the manager into camp. It should clearly be the other way around, but is that really so surprising considering this organization’s inability to do much right?

But we’ve probably covered that ground sufficiently, and it what it is now. Nelsen will take over on Feb. 1, which gives him about a month to sort out his depth chart, to assess who needs to play where – where does key man Torsten Frings best fit, for instance – to establish expectations on the practice field and on game day.

Yes, Nelsen has a long season to do all that stuff. But considering TFC’s history, and how the fans might be understandably jaded, the process will go much smoother if they don’t start slowly in 2013. Otherwise, everyone will suspect it’s more of the “same old.” And that’s not what TFC needs.

Does Eric Hassli want to be in Toronto?

Did he ask for a trade? Hard to know. The big striker insists he wants to stay – although he can’t have been overly pleased with the hardline stance of new president Kevin Payne. (Payne said the club would decide where Hassli plays this year, not the other way around. So take that.)

If Hassli does call BMO Field his home this year, he could find tough sledding once Danny Koevermans is at 100 percent speed and fitness. Even if Nelsen wants to play a 4-4-2, he doesn’t really need two target men; Hassli and Koevermans are fairly similar.

Is Stefan Frei ready to retake his spot?

Frei stood tall behind some pedestrian 10-men outfits at BMO. So his devastating ankle injury last March put talented understudy Milos Kocic into the starter’s seat.

Frei is back and apparently the starter (and Kocic isn’t too happy about it). So is he as sharp as before? Is he confident? Does he have the team’s confidence?

If Frei wobbles, or if those repaired ankle ligaments prove troublesome, Kocic has proven that starters’ ability rests in those gloves.
