Of course it is not only us that know about Sol's situation and it won't only be us who are interested.
The most important thing for us is that in that last hour of the window that we have a squad in place that will take us through the last period of this season which will be a very demanding period.
"It will also be a period where the other teams will be strengthening and deciding what they need as they address that last period of the season themselves. We have to make sure that we are right come that last day."
Hughton was speaking ahead of this Saturday's game against Watford at St James' Park, which will give his team a chance to consolidate pole position in the promotion race.
"Everyone is pulling in the right direction at the moment but what we have to make sure is that now we have gone through a phase in the season where everyone has done well and things have gone for us," Hughton added.
"The only way we will be able to sustain our run is to be able to do the same things. That is the players lifting the supporters and the fans backing us in the way they have done.
"We went through a period where we drew two games at home and lost twice away and it was always going to be about a reaction coming back from that and I could not have asked any more for the players.
"The job is certainly better when you are winning matches but along with that comes the pressure of sustaining it."
