There are different ways of looking at it. One of the things in my mind is how easy it is to get back to Merseyside to see his family.
Newcastle to Liverpool is quicker on the train at just under 3 hours. Both flights and trains with Glasgow are around 6 hours. On the other hand, flights from Paris to Liverpool are around 2 1/2 hours, Tuchel apparently having fallen out with PSG.
On the other hand, there could be a vacancy coming up closer to the Wirral. I can't see the manager staying for too much longer at Fleetwood.
