Like most managers unlikely to ever coach a top club he'll probably be interested. While I'm sure he, as someone who has managed in the PL, got some money in the bank I think he would struggle to say no to secure the future of his kids, grandkids and grand-grandkids with a fat Newcastle contract.
Howe would jump at it.
He only needs to keep them in touch until the end of the window and he will fancy himself to do that.
After that with new riches the brief then becomes to stay up which odds in his favour with a good window.
This buys him more time and another transfer window.
If he can then get them top half his CV is improved and worst case is a multi million pound pay off.
Don't think hes the man to get the next stage but could see it working all ways.
Good job for someone like him
