Silva benching DCL next season would send a terrible message. He's been tasked with a really difficult role and has passed the test with flying colours. If Silva casts him aside next season then what impetus would their be for other players in the team to get their heads down and work hard? Hard work and successful application on the pitch simply HAS to be rewarded with further minutes, otherwise what's the point?
I'd understand if he'd been meh this season, but he really hasn't. People harp on about the goal tally, but he's actively helped create a lot of goals even if it wasn't him ultimately sticking them in the net. It was his touch from Digne's throw in that set up the Richarlison goal for instance
If Silva wants to bring in another striker as competition for Dom then that's perfectly reasonable, but that striker shouldn't then just walk into the team. The gig should be DCL's until the other striker proves that he deserves to replace him, and if he doesn't then Dom should keep the job
I actually think he'll score a bigger total of goals next season, but the big thing to pay attention to will be the hand he plays in other players scoring. If he's helping make the goals go in then it doesn't matter if it's him, Richarlison, Sigurdsson, Bernard, Coleman, Digne or Gomes being the ones to get the ball over the line. He'll have done his bit in just getting the ball in the goal, even if he hasn't personally scored
And perhaps (Sit down for a second because I think this might blow some peoples minds) if we do get another striker in, maybe Silva could try the wild and unprecedated tactic of playing TWO strikers TOGETHER at the SAME TIME!!
