Mud guards on Trek Alpha 1.5 2014 problem

[Dogzodiac]

Which mud guards are the best for this bike as there seems to be very little clearance between the rear wheel and the seat tube?

I had a 1.5 a few years ago and went with sks race blades.

SKS race blades,or etc clip on road guards neither of which go under the brake arch.
