I disagree with this mate. Simply because the likes of
@davek and I do take the licks in respect of his second and third season. Further, we both concede that he was right to be sacked. What we ensure though, probably to the point of boring a large volume of the GOT family, is contextualise his performance as manager. We do this specifically in relation to those that say Martinez was a poor manager. Some even go as far to say he was as bad for the club as Mike Walker. Which is utterly bonkers.
What I believe, with absolute respect, is that you too - along with
@Saint Domingo - are showcasing revisionism. For example, here you say:
"What went on over the next 2 seasons in the league was a disaster and a lot of it was caused by the manager himself."
Yes, some of it - and you use a good example with Southampton away - was down to him. Martinez nor his 'fans' can escape that. But what about the fact that he had no money, certainly where comparing to the funds in the hands of Koeman and Allardyce.
At the end of season 1, he had Distin and Howard fall off a cliff form-wise. Remember Distin vs Swansea away in the league cup early into RM's second season? Absolutely atrocious. Howard too went from a great season to a very poor one. Without any hint his form was to take such an alarming dip.
What would any manager do in that instance? He'd go out and buy a new CB and a new GK. He clearly didn't trust Joel as a number 1 (and said so publically). There is nothing wrong with buying a number 2 goalkeeper for emergency purposes only.
Where were the funds for this? He'd just saved 2 windows worth of cash / sales to bring in Lukaku for 28m.
"Yeah but what about Niasse". He had 13m to spend on a striker. It was a risk. If he had 25m to spend, would he have brought in Niasse? Of course he wouldn't.
If he had £10m to spend on a CB like Koeman did on Williams, would he have brought in Alcaraz on a free? If he had £27m to spend on a further striker, would he have brought in Kone for £6m?
You cannot compare apples and pears. What is completely reasonable is to say that he inherited an ageing squad and got a season out of them that he had no right to do. His second season domestically was poor but I for one enjoyed us blitzing Wolfsburg home and away.
Third season, again not good enough. But again, he had peanuts to spend. Cleverley on a free. Deulofeu for 4m. Niasse. Funes Mori. He had to spread a very limited budget across an entire core.
Could he have done better with it. Possibly, I wouldn't disagree. To say though that everything was plain sailing yet he blew a hole in his own ship is just factually inaccurate.
