Newcastle are three weeks out from the new season and set to welcome Matthias Jaissle to the club as Eddie Howe's replacement. The much-loved head coach is calling time on his Newcastle stint, months after the first knockings of discontent. FourFourTwo understands Howe was ready to walk after Newcastle's 3-2 defeat by Brentford back in February. The club's hierarchy have been able to line up a replacement, because they know Howe reached his limit some months ago. On the surface, what finally convinced the Newcastle boss to walk away appears to be a 4-1 pre-season friendly defeat to Championship side Bristol City, but this was far from the decisive blow.
