Tomatoes after potatoes- asking for trouble?

Last year I had Charlottes in this particular spot. They did look pretty ropey by the time I harvested, although the tubers were fine. We had blight on the plot which certainly affected tomatoes, not sure about the potatoes.
If I plant my toms on this patch is that a bad idea? The only alternative space will be partly shaded due to a large cardoon. But I grew sweetcorn there last year and then put mustard over the winter which I dug in 6 weeks ago. Any advice welcome!

Thanks mum, that has swung it for me, I’ll put the little princesses near the cardoon.
