All eyes will be on Tottenham Hotspur Stadium today as the transfer window closes later this evening.
Initially saying that it would be a quiet month for the club as he was very happy with the players at his disposal, Jose Mourinho has actually been quite busy in the transfer market.
Gedson Fernandes was the first to arrive as he joined on an 18-month loan deal from Benfica, with the club then moving early to make Giovani Lo Celso's move permanent after some excellent displays in recent weeks.
Steven Bergwijn, who Spurs had been keeping a close eye on in the past, then followed the next day as he joined from PSV.
It does tend to be a bit manic at Tottenham on deadline day and everyone will be hoping that is the case as the club really do need to bring in a frontman in wake of Harry Kane's hamstring injury.
However, things could become quite a bit tricky for the Spurs head coach if there is more than one arrival on deadline day.
Champions League football returns next month and that means Mourinho will need to name his Tottenham squad for the knockout phase of the competition.
Mauricio Pochettino found this problematic in the past due to the rules that state only 17 'foreign players' can be included in the 25-man squad.
This looks like it will again be the case following the additions of Gedson and Bergwijn, as well as the potential arrival of a foreign striker given the links with Olivier Giroud and Willian Jose.
Mourinho will also be forced to make a tough decision if two players sign on the dotted line before the 11pm transfer deadline.
Clubs are able to change their European squads before the knockout phase begins but they can only register a maximum of three new players.
Gedson and Bergwijn will take two of the three spots up, with the final place going to a new striker if one comes in through the door.
The addition of a fourth player and that would mean that one of the January signings would have to miss out on selection for the knockout phase.
Spurs captain Hugo Lloris currently isn't part of the squad for the Champions League after he was deregistered in October for Michel Vorm due to the dislocated elbow he sustained at Brighton & Hove Albion.
The good news for Mourinho is that he won't take up one of the three spots for new players as he can just replace the Dutchman, with Article 45.04 in the Champions League regulations stating that once the goalkeeper is fit to return again he can resume his position in place of the nominated substitute.
Tottenham will be back in Champions League action on Wednesday, February 19 when they host Bundesliga leaders RB Leipzig, before then travelling to Germany on Tuesday, March 10 for the second leg.
