Some other moves I missed in the last few weeks:
Atlanta United signed Cubo Torres from Tijuana. Once a big prospect for El Tri, he hasn't panned out and has bounced between MLS and Liga MX. He did score double digits for Chivas USA in 2014 and for Houston in 2017, but it's been a long time since he's had anything approaching a successful stint in Liga MX. In any case, Atlanta are in upheaval and badly need a replacement for Josef Martinez for 2020. Torres could be better than Adam Jahn, so it's something.
Atlanta will be able to use Jurgen Damm when the regular season starts up again, too.
LAFC parted ways with Adama Diomande, who cited family priorities. That leaves a hole at CF for them, although Bradley Wright-Phillips is still showing signs of life despite being old.
NYRB signed Ghanaian forward Samuel Tetteh on loan from Red Bull Salzburg. They have Brian White and Tom Barlow, who are both okay at best. Not sure whether players who aren't integral to RB Salzburg are good enough to meaningfully change the situation, though. NYRB has gotten such players on loan in the past and IIRC none have been too impressive. The narrative that Red Bull is neglecting this team feels real to me.
Minnesota signed Bakaye Dibassy, a 31 year old CB, who spent the last three years with Amiens in Ligue 1.
