FWIW - the situation was not helped by goalkeeper discipline & concentration.

Without sounding to technical goalkeeper gloves all have limitations that can lead to ball slips.

The main weakness is the potential loss of grip due to the tacky latex substance on them drying out with wear & the finger protection inlays on gloves which can reduce the keepers feel of the ball.

My brother has a warm water spray bottle in the nets which he sprays onto his gloves throughout the game as he is encouraged not to spit into his gloves.
Finger protectors are varied & personal choice dictates styles required.

After viewing the above youtube close ups hes sure the gloves were the problem onto actually gripping that spinning ball.

So another one of those situations where banner headlines of genuine keeper mistakes takes precedent over a succession of natural contributing factors that can & do occur with a ref not ideally placed for making split second calls.
