Here's where I think our problem lies and building upon what other people think:
1. Mourinho - He's an absolute legend but he's always been conservative. I don't know whether it's Mourinho's tactics, our slow central defence or both but we never seem to dominate a game in terms of decent possession and or incisive attacking play in the bigger matches (we play so deep and always need at least 1 dm to shield them). These are nearly always tense affairs and we never try to take the initiative which is so frustrating. If this is how he wants to play, by soaking up pressure then we need more direct and pacey counter attacking play as i feel we're stuck with personnel that aren't suited to this (we normally just hoof it to Costa, or pass it out wide to Hazard and expect him to run all the way). I guess if its been working for him all this time and he's getting wins they this won't bother him but maybe Jose could be doing more if he evolved.
2. People say we need a better squad (bodanki and a few others). For me it's not our backups, Remy is solid, Mata was one of my favourites, Cuadrado, De Bruyne, Salah who is killing it at Fiorentina, Schurlle. The list goes on. Jose just doesn't rotate effectively or integrate the reserve players effectively enough. He's pretty much played with the same core 11 and they are shattered.
3. We have first team players who maybe are tired or not talented enough at the moment. Dave is our best right back IMO. Luis our left back. Ivan's been great but for me he gets done too easily by tricky wingers. Maybe this is down to him attacking so much but i'd prefer Dave there, or if Ivan is there then we can't have Cahill as well who i feel doesn't have the 1v1 defensive ability to cover Ivan. Oscar for me never convinces me. Every now and again he will score a couple of goals but he's a very poor version of Super Frank. I know people aren't fans of Willian but I am. He was a box to box midfielder/free role am at Shakhtar and for whatever reason we've shoehorned him into a right wing position. He's got loads of pace to burn, an okay shot and has really high energy with a good pass. I'd try him in cm or am over oscar.
4. Cesc at CM. I'm not opposed to this at all as he's a great play maker and technically great. However, in the game big games, this leaves Matic with way too much to do. He isn't athletic enough to cover and the spaces and he's tackling, pace and strength just means people shrug him off so easily on the counter. He's often on alongside Hazard (he normally puts in a great shift but with all the dribbling he does towards the end he just gets too tired to defend properly) means that we cannot just park the bus which is Jose's default mentality. We can't do this effectively when we have these 2 plus Costa (we don't expect our striker to be defending all the time) are all on the field and I can't see why he doesn't see this. If we do have Cesc in i'd like us to give him a free role to do what he wants and play to box to box midfielders (matic and one other).
