We have played multiple games without Navas in the past so I think the team should obviously be able to harness another approach without him. I know Navas has dominated our offense over the last few months and although that right sided guarantee, which he brings is an obvious tactical advantage, there are many frustrations with it e.g crossing . The team will have to phase that out as the main attacking design and as I have said, we played without that in the past and we should be stronger without it albeit we will have to play a different way with Zabaleta's attacking even more important. Our right sided attack, still, is a major part of our play be it Navas or Zabaleta or even Silva or Yaya drifting out there to create something.
I think the issue here is that there are many players on the pitch that are not 100% fit and it is showing. We need to up the tempo.
