There are problems all over the pitch for Spurs, who are 14th in the Premier League table, but they have not been helped by the number of long-term injuries suffered in attack.
Frank admits he and his coaching team, who added John Heitinga to their ranks on Thursday, have looked at the data, particularly deep runs, to try to assess their issues going forward.
In Gallagher, though, Frank believes he has a player who can carry the goalscoring burden in the absence of Richarlison and Solanke, who is still working his way back to full fitness.
“I think he's very good to get on the end of chances, and also I think that to have a midfielder who can add goals is a huge quality because of course you always say you need a striker that scores 20 plus goals, but in reality you just need enough goals in the team,” Frank said in his pre-match press conference on Thursday.
“These days, it can be a winger that is the top scorer, so to have a midfielder that I think can add a good amount of goals in a full season is a huge quality, and especially his ability to arrive in and around the box, whether we are banking teams in or from high-pressure situations. He’s very good at that, and I think he’s a clever finisher.”
In a season of struggle, the development of midfielders Archie Gray and Lucas Bergvall has been a rare bright spot for supporters - the pair have started 18 league games between them.
Gallagher’s arrival has raised concerns that they could see their minutes limited, but Frank, who bemoaned his side’s lack of options in midfield last weekend, says the club’s decision to move swiftly to bring the former Chelsea man back to the capital was taken in light of Rodrigo Bentancur’s hamstring injury.
"I think any club you need enough competition and quality,” he continued. “Right now, it is like we swapped Rodri (Bentancur) for Gallagher, and before that, both Lucas and Archie played a lot of minutes.
“They are still in a great development (stage), and I think they are doing a lot of things right. There are not many 19-year-olds playing central midfield in the Premier League, so that talks a lot about their quality and also a little bit about how rare it is.”
