I think his first season showed what he can do with a defence at the top of its game.
Sure, he was lucky that Howard, Distin, Jagielka, Baines and Coleman stayed injury free and were playing top stuff, but I think that's what you have to accept with Martinez. He needs a set of players throughout the spine who know exactly what they are doing and are playing well/injury free. It then gives the rest of the team licence to excite.
Look at what happened after that first season:
Howard - cliff, fell off
Distin - see Howard
Baines/Coleman/Ovideo - Poor fitness/injury record
McCarthy - hasn't kicked on
Barry - nearly died from all the games last season
Atsu - what is it?
I think too many things happened last season that would have been difficult to predict. Your in the summer before last season started having seen that team play like that and you surely can concede that it would be reasonable to think "right, get Lukaku in with the money we have and let's go again". It didnt, and he has no cash to do anything about it and, in his words, he spends it all on Lukaku.
At the beginning of this season he has got to find:
A right winger
A right back
A goalkeeper
A CB
A CM
A left winger
And guess what? He's got no money. If he did, he would have spent it. And I don't mean zero pounds, I mean he has no money to buy proven replacements, so he reverts to youth/cheap options:
Lennon - £4.5million is, in this era, a steal
Deulofeu - £3.3 million wasnt it? or something outrageous?
Funes Mori - 9.5mil because, reportedly, CP wanted £15mil for Dann
Clev - Free and can play a variety of positions
So he spreads his small 'fortune' on as many players as he can. I think he brought Lennon in because he knew Deulofeu would falter - as he did.
Who else? Matty Foulds? Shani Tara-whatever? (Niasse to follow) I may have missed someone but I am rushing!
I understand Niasse is used as a negative. I dont understand it but I dont believe we spent 13.5 million up front on him. As people have said, 13.5 is an outrageous amount of money which leads me to believe if we had spent that amount of money, he would have to play him. He's under no pressure to so at the very least it's staged payments with add-ons. Just my opinion anyway.
In my opinion, we have spent NOTHING which warrants the clamour for top 7. So for his money, what have we had. Inconsistency - without a doubt BUT:
At times we have played scintillating football that hasnt been seen at our beloved GP in years. It hasnt been often enough, granted, but we've seen glimmers of what he wants - fast, possession based and counter-attacking football. If he has the cash to bring in players at the back through the spine who can keep us solid when we are under the cosh, then the benefits are there to see.
I think its irrefutable that with:
A top GK
A top CB
A top CM
A top LM
All with PL experience and/or league winning experience that we wouldnt be challenging that top 7.
Do I think he should be given the opportunity to bring those players in? Yes
Do I think he will? No
Do I think he can have any complaints? Very few
