There is also car parking south of the stadium on Stanley Matthews Way between Screwfix and the Stadium opposite Pets at Home (Sat Nav ST4 8GR). It costs £5 and always has spare spaces (Capacity 250 but never full). You can get to this car park via Stanley Matthews Way from the A50 or Trentham Road.
After the match all traffic goes south which means you avoid all the congestion by the stadium. It may take a few minutes longer to walk to but the exit on to Stanley Mathews Way and out on to Trentham Road is quick.
