I asked for examples of teams signing players in January to keep up their tempo. Not for examples of clubs that hypothetically if they had signed some unknown player potentially perhaps could have kept up their tempo...
I think our business this summer (and last summer, and last January, + our excellent development work) is what will give us a chance to keep up our tempo. Similar is true for Arsenal imo.
We still have Son settling in, Pritchard coming back from injury, Chadli has been pretty much a non-factor so far this season and the same is true for Bentaleb. We have real cover and competition for places in most areas. This has happened through very good squad building over the last 18 months with a focus on player development and a bit of patience.
Looking for a January transfer window fix to what isn't broken is for me very much the wrong way of approaching things. If we can sign someone good value with the ability or potential to be a long term solution and improvement for us of course we should go for it. That's what's brought us this far, more of this seems like a good way to continue.
