Pochettino, mindful of the club's impending move to a new stadium, has previously refused to question the funds available to him but failed to hide his frustration when quizzed ahead of Spurs' home game with Newcastle United on Saturday. "But we are in a very good position and we will fight until the end to be as high as we can".
Things got ever more hard for Tottenham when Craig Cathcart headed the Hornets into the lead, and as time was beginning to tick down it appeared as though it might be one of those frustrating evenings for Mauricio Pochettino and his men.
"It was hard because I had a big chance, normally, in 10 chances (like that) I'd score nine but sometimes the ball doesn't want to go in", he said.
One man who could finally benefit from Spurs' quiet transfer market, however, is Vincent Janssen.
As well as issues off the field, Pochettino has also had to contend with numerous injury problems with Harry Kane and Dele Alli both now sidelined, as well as losing Son to two worldwide torunaments since the start of the season.
And as a result, Janssen has been allocated a squad number and named in the club's Premier League squad following the departures of Mousa Dembele and Georges-Kevin Nkoudou.
"People get a bad feeling, not any manager or player, you know why players arrive in the first team?"
Yesterday, images of Kane during his rehab emerged which led some to suggest he could be back to lead the line for Spurs sooner than expected.
He said: "I can not tell you if he is ahead of schedule or not. We are still there, we're going for it", Son is quoted as saying by the Daily Mail.
"He is showing on his social media that he looks strong and very fit and very well, running and doing exercises". We will see, we need to assess day-by-day, week-by-week but we are happy with how he is recovering.
