It must be terrible that nobody from the MLS has even made an offer for khedira and or higuain yet
Their contracts are too big. The highest-paid players in MLS in 2019 were Zlatan ($7.2m), Bradley ($6m) and Schweinsteiger ($5.6m). Higuain and Khedira are on $8.9m and $7.1m respectively. The issue of DP slots is always there.
Besides, there are few actual big-name DPs in the MLS. Since Zlatan left the highest profile foreign players there now are Carlos Vela, Nani, Victor Wanyama, and Matuidi.
Who knows, maybe Miami or another team with a large hispanic fan base like LA or Houston can take a gamble with Higuain. He could score lots of goals there if he can get fit, but it's a physical league. Nothing can save Khedira, he's broken.
Chinese money rule change and Covid-19 really fucked us here.
