The five teams qualified for this season's Concacaf Champions League will begin their official preseasons on Saturday, which means real-life games are almost back.

LAFC, Atlanta United, NYCFC, Seattle Sounders and Montreal Impact are among those beginning their preparations for next month's CCL matches. But as we all know, their rosters will likely continue to change as those games draw closer.

So where does each club's squad sit at the moment? Let's dive in...

Atlanta United

It's never boring around Atlanta United. 

The club have seen vital first-teamers Darlington Nagbe and Leandro Gonzalez Pirez depart, while squad members Justin Meram, Michael Parkhurst, Florentin Pogba, Dion Pereira and Brandon Vazquez depart, among others. They've had a public contract impasse with right wingback/soccer's swiss army knife Julian Gressel while trading for similarly versatile right back/right wingback/right winger Brooks Lennon, signing him to a new contract. 

Behind Lennon, the club permanently acquired midfielder Emerson Hyndman, re-acquired defender Anton Walkes and signed center back Fernando Meza within minutes of officially transferring LGP to Xolos. They now have 22 players under contract, expect more movement over the next month. 

Biggest hole: Well, given they still have Josef Martinez, the attack is fine. Nagbe is a unique commodity, but the club's midfield isn't devastated. Defense still has breakout star Miles Robinsonand the hope is Meza can step in for LGP seamlessly, though that's no easy task. Depth, though, may be an issue. 

Who is the backup center forward? What happens with Tito Villalba and Gressel? George Bellolooks to be the best choice for LB/LWB, pending the system Frank de Boer chooses, though has played only 177 MLS minutes. For a team in CCL, with aspirations of competing on all fronts, it's not ideal. 

Projected starting XI today (3-4-2-1, right to left): Guzan; Meza, Robinson, Escobar; Gressel, Remedi, Hyndman, Bello; Barco, P. Martinez; J. Martinez
