Weve improved the full backs 100%. Lallana also looks good. Lallana is basically an extra body, he isn't however a massive improvement on what we had. i.e Steling and Coutinho.
Weve spent 20m improving the LCB position and ended up no better off. We should have signed a DM who can fill in for an ageing Gerrard. Please don't say Lucas, as much as I love the lad. However up front has been a disaster. Weve replaced Suarez with Sturridge who as expected, gets injured a lot. Weve replaced Sturridge with Balotelli. Square peg in a round hole.
So in short we;ve improved the FB positions, added depth and similar quality to out AM options and massively downgraded on Strikers.
Ive not really included Markovic. He obviously been poor, but he may come good.
We've improved our fullback areas.
Lallana is class and was needed given all the games we will probably be playing.
Emre Can was brought into replace Gerrard in the long term. Too early to judge yet, but he did look good against Spurs.
Lazar Markovic, although he hasn't set the house on fire, is very highly rated around Europe. I'm sure he'll come good, just needs time to adapt.
Upfront I agree, we made a massive mistake not bringing in another mobile forward.
The transfer window has hardly been as bad as you've made it out to be though.
