haven't seen enough of either to make that judgement, but surely we can use Scamacca as well, Morata and Kean haven't been living up to expectations and we're begging for a striker that can bring in more goals.
stats wise Abraham and Scamacca have been pretty similar in Serie A this season. Abraham has 6 goals in 1500 minutes in Serie A, Scamacca 6 as well, but in 900 minutes. Abraham has 9.36 xg and Scamacca 4.57 (which is to be expected given the difference in minutes and chance creation between Sass and Roma).
