The 20-year-old’s first senior goal for Palace – albeit in non-competitive surroundings – ended up being the winner.
But Kaden Rodney also went close with a deflected effort from distance, whilst Sarr himself caught one late effort clean on the half-volley – but his effort faded beyond the post and into the side-netting.
A valuable exercise for Palace and a win by the same scoreline as the previous season; should this season proceed to carry the same finale as 2023/24, Eagles supporters have much to look forward to in the weeks and months ahead.
