SR need to choose a manager they can commit to for a period of time (or until Spurs poach them). Future planning is knowing who you're going to look at next but if the list is of the quality of the last 4 appointments we're going to struggle. Russell Martin, for all his faults, was the closest we've got to someone we might stick with. The downside was he simply wasn't ready for the Premier League and had zero intention of adapting or being pragmatic. Since SR came in, it's been a horror show of poor recruitment both at manager and player level.
This summer we'll begin to get an idea whether Spors might be the answer to this though next year whatever we do will be somewhat flattered by the league we're playing in.
