Right, okay. I'll give you Yossi, fair enough. But Ramires? Hardly a creative, thoughtful attacking player. He's more of a dynamic box-to-boxer, something which admittedly Lampard is accomplished at, but Ramires fails on two counts. One, Lampard is Chelsea's main attacking outlet: much of their play flows through him. Ramires has neither the passing nor the vision to perform like this. Two, he's far more defensively minded than Lampard, more of an Essien.
As I said, you need like-for-likes to fill gaps. You rightly mentioned Benayoun, and I will admit I had forgotten about him. However, my point still stands: your replacement for your vitally important 32 year old central midfielder, a 30 year old, is crocked. With Arsenal, this'd be fine: Nasri, Wilshere, Ramsey, Rosicky, Arshavin all fill this role with ease. Manchester United have Scholes, Anderson, Carrick; ****, even Park, Giggs and Gibson.
Also, your point about Zhirkov is rather illustrating my point. When you're resorting to playing a left back/winger in central midfield, things are badly wrong. What I expect Chelsea to do is buy a decent backup. Someone of decent stock, fairly young and with good potential, someone of the Renato Augusto mould, perhaps?
I also forgot about Yossi until a few weeks back when someone mentioned him. Notice how I said if we get an injury in the centre of the park those two players could come in for us. I didn't say they both would come in for just Lampard in particular. As you said, Ramires is more similar to Essien and doesn't offer anything going forward really.
Agreed that we lack depth compared to the other top teams in the league. Last year we had Deco, Ballack, and an injured J.Cole as backup, they all were decent going forward and could fill in for Lampard. We've replaced those with Yossi who is out, and Ramires. So effectively (excluding Yossi and J.Cole) we have sold two decent attacking midfielders and signed one defensive minded player in Ramires. We also had Belletti who could play in the midfield, and he even does more going forward than Ramires even though he is naturally a defender.
Ancelotti said he would look to youth more this season but we should have atleast a few more players with experience to fill the bench if the worse comes to worst. Regarding your suggestion to sign Renato Augusto. I haven't seen him play in real life but I've heard good things. We coud also recall Nemanja Matic from his loan spell in Holland if things get worse.
