Soldado arrived at White Hart in the summer with a £26million price tag and a hard-won reputation as one of La Liga's most lethal finishers.
But although he has found the net 10 times for Spurs in 24 appearances, just half of those goals have come in the Barclays Premier League.
More worrying is the fact that all but one of his league goals have come from the penalty spot.
The Spaniard drew a blank again in Saturday's 1-1 draw at Hull, who had threatened a shock win when £6.5million new boy Shane Long put the Tigers ahead having been teed up by fellow home debutant Nikica Jelavic.
The boost Hull received from their January signings was palpable, but Sherwood's faith in Soldado meant he never intended following them into the market.
"We're all right for strikers here. If we added more players to what we've got it would be impossible to train...too manic," said Sherwood.
"It's just a matter of time before Robbie hits the target again, starts scoring and gets on a run.
"He's a good trainer and he's just got to stick at it. We've all been professional footballers, so we know what it's like.
"What are you going to do? You have to keep training hard, working hard at it and it'll turn around because it always does.
"I'm sure it's not the first barren spell he's had.
"He was all right (against Hull). His hold up play was good, he had a few volleys - sometimes they go in, sometimes they don't.
"I'm not putting pressure on him and he's not putting pressure on himself."
With Soldado off target and Emmanuel Adebayor denied by goalkeeper Steve Harper with his best chance of the match, Tottenham relied on midfielder Paulinho for their equaliser.
The Brazilian was back in the starting XI for the first time this year following ankle trouble, and Sherwood was happy to have him back.
"He's been out for a while and he did well. Jan Vertonghen was back as well and he grew into the game, getting better as the game went on.
"We had Younes Kaboul back on the bench too, so with a few coming back to fitness by the time we play Everton next week we won't be too far off full strength."
While the efforts of Long and Jelavic on their home debuts will have left the Hull faithful in buoyant spirits about the remainder of the campaign, manager Steve Bruce expects it to be tense.
With his side two points above the relegation zone and three points off 10th, he said: "I've never known 10 teams stuck by three or four points.
"It's quite ridiculous. Usually you have one or two adrift by now. As I've said repeatedly, it's a marathon this thing and it's just about to get going.
"When the daffodils come up it starts to get a bit tickly, so it's all to play for."
