I've started a couple of new teams in recent months, and I concentrated on high Q 4* players when improving the squad, winnowing out the slow training 2* and 3* players in the process. With ground improvements as well, I still had a couple of million to spare at the end of the first season for squad improvements the next season. Bear in mind if you get into financial trouble the two players you mention will be the first to be sold (cheaply) to bale you out.
Also, with the primitive pitches at Level 1, the 'big shot' players will be prime candidates for the injury machine...
