#1 (Shouldn't) Liverpool have evolved since he left

There may be a reason why Liverpool have not replaced Philippe Coutinho. Yes, his contributions were key, but the team has grown without him. The acquisition of Fabinho was a smart one, as he has become the best defensive midfielder at Anfield since Javier Mascherano. Along with the advancement of roles for the likes of Georgino Wijnaldum and Jordan Henderson, the midfield cover Liverpool have at the moment is pretty good, to be honest.
Alex Oxlade-Chamberlain is back for the Reds and he will be like a new signing for Jürgen Klopp after a year out, meaning Coutinho is not a priority at all. Now, Liverpool operates like a perfectly-oiled machine without him, as all three midfielders share the responsibility of the dirty work in the middle of the park as they feed the ball to the attackers. If Coutinho were to come back, the shape of the midfield would force the workload on the remaining two midfielders.
The Reds have found the perfect balance in their team and there is no way that Philippe Coutinho would be a regular starter for them anymore. While his quality is undeniable, one thing we have learned from Liverpool's evolution under Jürgen Klopp is that they operate as a team and do not rely on individuals anymore. This incredible team spirit and mentality has won them the Champions League and has surely kept them motivated for this coming season ahead.
The Reds will challenge for major honors again this season, whether or not they re-sign Philippe Coutinho. Do you think the Brazilian should return to Anfield?
