^^That's not a mudguard - it's not even a smallpuddleguard.
P-clips and some creativity with re-bending and cutting the stays should allow full guards to be fitted for the rainy season. Extending the front mudguard with a flap will go a long way towards keeping feet & BB dry as well. Just allow enough clearance for proper mud / snow / whatever to not fill the gap between tyre and guard.
£15 or so isn't much to pay for arriving at work with a bit of dignity / not having a wet arse...
