What is so hard to understand when I said Wanyama is similar to Dier, or Janssen has similar abilities to Kane. That's my standpoint and tbh I haven't seen too many people who think any different so I'm not in the minority. That's why I ask you what is it that you see in them which is different.
About Poch and tactics. I think he has proven that he likes a certain formation and pressing tactic and he sticks by it. Yes I believe that makes the way we line up and play predictable and maybe opposing managers will find ways to stop us because of this.
Look, the advantage of signing back ups like Wanyama and Janssen who as I said are similar in ability to Dier and Kane is that they can easily slot in without causing Poch to change his tactics and system. I can understand that way of thinking. The squad is stronger and that can only be a good thing.
In my mind Wanyama is a TOTALLY different player to Dier. He is a 'bruiser' type of DM who is more likely to use brute strength to intercept players whilst Dier is more the 'Carrick' type of 'intercepter' who closes off attacking lines AND can spot passes to start counter-attacks. Dier also used to be a CB so his style of play is naturally different to Wanyama because of this alone imo.
I don't think i need to go into detail as to how Wanyama is different to Demeble..
In fact we don't have anyone like Wanyama in our squad currently.
Janssen by all accounts can play as a lone striker as well as across the front three, though his qualities are best suited to playing as a striker (solely or with a partner). To me this is slightly different to Kane who can play as the front man but also behind the front man (it seems he is better than Janssen in this area).
Who played regularly last season in the same way that N'Koudou is said to play?
I take a bit of issue with your assumption that these signings mean he will stick by what he has always done: He can now play 4-3-3 if he feel, with a CM 3 of Wanyama, Dier and Dembele or Wanyama, Dier and Alli.
The front 3 can be Kane, Eriksen, Alli, or Kane, Janssen and N'Koudou or Janssen, Lamela, N'Koudou et etc, lots of permutation in my mind here.
We can also stick to 4-2-3-1 if we want (and have greater depth), we could go two up front and a diamond, we can go 4-4-2 if need be.
There are a number of tactical variation opportunities that i see and i can't understand why anyone would assume Poch will simply 'stick to what he has done', esp given the
different attributes that the (probably 3) signings bring to the table compared to the players we have and used last season.
