@davek -
I tell you what, you come back when you can find an example of any manager at any club who ran up that club's biggest ever Premier League number of points and was sacked the next season for dropping into the bottom half of the table.
In your own time.
I can do better than that mate, I can give you 2 managers who got the can after having provided record PL points tallys, winning their sides the league title and got canned a year later and where nowhere near the botton half of the league.
Mancini & Mourinho.....
How about Redknapp guiding Spurs to their best ever PL finish and points total in 2010, brought 5th home the following season - plus a CL QF, managed 4th again the following season - and got canned in the summer.........
That's without even having a bleeding look. People live in the present, especially in football, as it's a results business.
