Interesting, but this also completely ignores transfer fees, has someone done a combination chart?
Not that I'm aware of.
The point of it was to ignore transfer fees, Moyes had a negative transfer budget over his recent seasons with Everton like Wenger at Arsenal. However, Wenger is often praised for operating on a low budget however the fact he had a good wage budget helped him immensely.
That said, what Wenger did was very good.
The graphs won't ever be accurate because even after a combination chart then you've got to control for European football and the need for a larger squad.
The reality is Wenger did well on his budget, Ferguson did well on his budget and David Moyes did well on his budget too. Martinez has continued his good work however whether he could build a team so well drilled like Moyes did only time will tell. And whether Moyes can build a formidable team when he actually has a positive transfer budget and large wage bill, too only time will tell.
Moyes got 63 points last season, however looking at the previous 3 seasons he went from 54 to 56 to 63 and so it looked like he was building himself a good little team there. Realistically getting around 66 or 67 points this season would be fair to predict for him.
The question then becomes had he a striker like Lukaku, how many more points would he be worth? Somebody posted here saying Lukaku's goals have earned Everton 12 points, that is to say turning losses into draws / wins and draws into wins. Therefore I wouldn't be surprised with such a striker if Moyes' Everton managed to get over 70 points.
Martinez is on course for 73.5 points however that would mean maintaining their excellent form even against Arsenal, Sunderland, Crystal Palace, Man United, Southampton, Man City and Hull.
In my opinion come the end of the season it might be the argument Martinez would probably be around the points mark we would have expected Moyes' side to get this season with a striker like Lukaku.
I personally think Moyes did well at Everton. I don't know if he is the right man here or not, therefore I am happy for the board to give him time but I will be nervous next season. I think his premier league performances between now and then end will give some hope, if he wins the remaining games. It's something he can do but the team will need to dig deep in some games no doubt. They are still fighting for Europa, something that would give our youngsters a fantastic european experience. And Moyes needs to learn how to deal with so many games in a short period of time, I think he struggled with this and couldn't prepare the team as well as he did Everton.
