If you browse this thread you will find that most of these teams have been covered quite well already in some way or another. I will summarize the teams you mentioned a little bit.Hello, What do you think Uae, NTT, EF, Astana, Movistar, Trek are all going to do on the transfer market? It is very quiet in terms of transfers with those teams.
UAE: Added Majka and Trentin already as very solid riders, expect them to continue to build around Pogacar by adding a few raw domestiques.
NTT: One of the bigger question marks, next to no movement yet, also no extensions announced yet, might be in the market for a big target.
EF: With Kangert and Woods exiting and the emergence of Daniel Martínez, they look very thin on mountain/GC riders, look for them to strengthen that department and also round out their classics squad a bit further.
Astana: After recent reports that López (confirmed) and potentially Lutsenko (would be a huge surprise) will be let go due to financial reasons, big question mark is who the team leaders will be next season. Since Vlasov is making big strides, expect them to put their faith in him and buy low this season. Likely they'll add a few talents and cheap domestiques instead.
Movistar: Are generally active on the transfer market a little later than other teams, should look to add more "second-tier" riders as they did with Mühlberger and Garcia Cortina. Have a lot of prospects but are still thin on domestiques.
Trek: With Porte, Nibali and Mollema all being 33+ years old, they might look to go younger soon. As for 2021 however, i would expect the same captains and just some new domestiques and prospects (they already signed Fancellu and Tiberi who I personally like)
