If Maresca was smart would've kept the group together see out the season and let them go in the summer, he clearly tossed some aside and has his favorites, and Chalobah return only confirms this. If we fail to get Top 5 he is the biggest reason why we failed, this squad has holes but is still good enough to get CL this season.
And honestly the reason he tossed some on the side so nonchalantly is because until not long ago CL wasn't even an objective he said so himself probably didn't even care to keep the whole group together just work with those he likes but when he saw fans angry changed tone.
