The clock is winding down and only a couple months remain before Atlanta United and Minnesota United kick off their inaugural MLS campaigns, and both outfits are working diligently to round out their debut season rosters.

A slew of drafts - super and otherwise - are now in the past, so here's what these new franchises need before MLS kicks off the 2017 season in March.

Atlanta United

Atlanta United is quite far along in its roster-building process, with head coach Gerard Martino already assembling 24 of his 28-man squad with a healthy mix of MLS veterans, Designated Players, SuperDraft selections and international signings. Here's how Atlanta could line up with no further changes:

That's not too shabby, at least on paper, but Martino could still use a few reinforcements:

Goalkeeper

Alec Kann and Alexandros Tabakis are both unproven options between the posts, and while both are certainly capable of stepping in, neither has enough experience to command an assured starting role; luckily, it seems Atlanta is already thinking ahead, having been linked with U.S. international Brad Guzan.

Striker

Kenwyne Jones has a lot of Premier League experience under his belt, but his on-field work ethic has always been a bit suspect. If mobility is needed up top, Martino doesn't have a quality second option to call on from his bench. Adding another striker with MLS experience would be nice.

Center-back

At the moment, Atlanta's full-back ranks are filled with a lot of competent options, but the club only has three center-backs in Michael Parkhurst, Zach Loyd, and No. 2 overall draft pick Miles Robinson. The first two are proven starters but depth could be an issue with only Robinson in support.

Minnesota United

Minnesota United is a little behind Atlanta in flushing out its inaugural roster, having penned 18 players thus far, many of whom had previously played with the team in the NASL. Minnesota has yet to sign a DP and still needs to add players in key positions. Here's how the team stands:

This XI features a few veteran pieces, some young and raw talent, and a few of the team's NASL standouts. Here's what head coach Adrian Heath could use:

Goalkeeper(s)

Like Atlanta, Minnesota could use a starting goalkeeper. Unlike Atlanta, the Loons don't actually have other options at the moment. Draft pick Alec Ferrell is currently battling fitness and also hasn't, well ... signed for the club yet, leaving Minnesota with a goalkeeping pool of zero (0) from which to choose.

Forward

Minnesota is in desperate need of more attacking. The current first-choice option is Christian Ramirez, a proven goal-scorer in the NASL who's never played in MLS. While he's highly touted, it's unclear if Ramirez is enough for the Loons, who could really use some assurances in an otherwise thin squad.

A Nordic Star

Minnesota United has something of a Nordic flavor, having penned Finnish midfielder Rasmus Schuller, Norwegian defender Vadim Demidov, and Swedish midfielder Mohammed Saeid to its roster, while being linked with Danish striker Bashkim Kadrii and Swedish 'keeper John Alvbage.

We're not quite sure where Minnesota's affinity for Vikings comes from (though we have one guess) but if that's the identity the club is building, a star signing like Johan Elmander, Jonas Olsson, or Nicklas Bendtner would be perfect.

Then there's Zlatan Ibrahimovic.

The big Swede is busy dominating the Premier League at the moment, but since he's already gone ahead and conquered England in just three months, maybe he'd like a new challenge come summertime.
