‘That’s Entertainment’ blared out over the public address system pre-match at Craven Cottage; The Jam’s 1980 hit was a premonition of what was to come.There was a certain irony, amid the madness of a thrilling five-goal game, that Crystal Palace’s goals all came from left wing-backs. Firstly, Tyrick Mitchell’s unlikely brace, then his replacement Ben Chilwell’s slightly scuffed shot to win it. It was that pair who brought the fun, but Palace’s defending left plenty to be desired. Chaos has been a feature at Palace in recent weeks. Their busy transfer deadline day had followed two defeats in which they conceded six times, often being picked off in transition. When two more goals were conceded against Fulham, albeit answered both times with Palace equalisers, it felt like that theme would continue.Pierre Sage has his first points as manager, and his preferred style of play has already become clear. What happens in the weeks to come may tip the scales in his favour as it did in bizarre circumstances here, but he will have to find a happy medium on that risk-reward scale given he appears to want to play a style that has a strong attacking instinct.Palace will, and already have, come up against teams who will punish them for slack defending. That is the area most in need of remedial work so far, and may see them heavily defeated at times this season. But they probe forwards with speed and purpose and have the players to create chances.Tyrick Mitchell scored an unlikely brace for Palace (James Fearn/Getty Images)Wasting those opportunities was their failing against both Everton and Manchester City, but it was rectified against Fulham, only for the defensive problems to be starker than before. Sage had said in his pre-Fulham press conference that his team played the way he wanted for longer against City, and this style of play will take time to embed, especially with 11 signings, of which four came on deadline day.
