In our last two PL winning seasons, possession, fast accurate forward short passing, tenacious regaining possession from the front and fast, brilliant wingers gave us a winning formula. Teams then began working us out by sitting back and playing on the counter. It became obvious that our defenders lacked pace (Walker excepted) and Rodri and Gundo lacked the control that Fern had previously given to break up counters in the middle of the pitch.Losing Sane (injury then transfer) and replacing him with Mahrez, losing Aguero to injury and Jesus's inconsistency (though on form he is excellent at it), all took away much of our intensity and pace up front. Arsenal, Southampton and Lyon all exploited this recently. Thinking about yesterday, lack of basic defensive instincts from 3 players led to the penalties but if you take the penalties away it was still a winnable game. We probably (?) won't concede 3 pens in the same game ever again. So, the job in hand is to realise where we're going wrong in the last 12 months and move on. With a back 4 of Walker, Dias, Laporte and Ake the defence will improve. Upfront Aguero, Jesus and Sterling give us enough quality. KDB is our best player by far, Foden and Bernardo are good enough. Fern has been good enough but ageing. So the weakness for me lies in defensive central midfield. I hope Rodri can do it but I'm not sure he can. I don't think Gundo can handle that position on his own especially in big games. So if we were to sign another player, that is the position needed - in my humble opinion of course. If we need the money for a big buy I would view any but not all of Garcia, Mendy, ZInch and maybe even Mahrez as potential income or expendable carrots to dangle to selling clubs. Lack of leadership on the pitch? I'll leave that to another post!
