Front Chainring

I need to replace my worn front Chainring, Shimano 105. The existing one is FC-5800 50 tooth which I cannot seem to find anywhere. Do you know if the FC-R7000 is a compatible replacement?

Thanks.

Spa Cycles will have one.
And it doesn't have to be Shimano, as long as it's compatible. I went 48/32 when I changed chainrings, first because it's quite hilly round here and second because the number of times I can spin out the 48 is negligible.

It would need to fitthe 4 arm spider though.
