I would give Strand-Larson a chance with our best attacking/creating players around him for at least a run of ten games and then see where he is. He has not had that yet at Palace. Mateta has had support from Eze, Olise, Sarr, Munoz, Mitchell, Kamada and Wharton at one time or another and we still only got one good season out of him for goals.
I'm not saying JSL will be a bigger success than JPM. He might not work out at all but he has started getting in positions to score and has now got what? 3 goals? 4? in 6 appearances. At least 3 of those appearances he did not play the full game.
Strikers are confidence players. Goals tend to boost confidence making it more likely that he'll score, and so on.
For me right now you have to start him and be patient. Its not as if our alternative options are more attractive.
