Former England striker Shearer weighed in on the situation, speculating that Slotâs remarks may have been influenced by something more than just Nunezâs erratic finishing.
"I donât know Darwin Nunez as an individual, but I understand the manager being frustrated with him, because of the chances he misses," he said during an interview with Betfair.
"Heâs not a natural finisher, however, having said that, I remember when he came on at Newcastle a year or two ago, he scored two great goals. His finishes were magnificent then."
The Premier League legend also raised the possibility that the criticism from Slot stemmed from issues beyond just match performance.
"Itâs not often you see that sort of thing from a manager, but I donât know whatâs gone on behind the scenes before, or if anything has gone on in the dressing room which we donât know about," Shearer added.
"Maybe he doesnât like what heâs seen from Nunez in training and is trying to get a response out of him. I canât remember a time, if any, where a manager would have criticised my attitude or work rate."
