I'm not really anyone is talking up TW as "the next Klopp" however you're a bit harsh in your St Johnstone summary. You missed out the multiple qualifications for European competition, which resulted in a 2-legged over Rosenborg, and a Scottish Cup win. Like I said, he's next the world's greatest manager but he's a known quantity at this level, and well proven. Considering the mess we're in just now, I fully understand why many are looking towards him as an ideal candidate to sort out our current mess.
If you're of the opinion that club should go for the lucky dip option of Alexander or Grayson, you're more than entitled to do so. It might end up being an inspired choice, like McGhee first time around or McCall. Or it could be a disaster like Gannon or Baraclough. Seems a strange time to take a gamble though.
We'll just need to see who came out on tops in today's interviews.
