Saturday's 1-0 win over Crystal Palace means that United are now just two points off a top four spot, with new signings such as Luke Shaw, Daley Blind and Angel Di Maria settling in nicely.
Despite spending £150m in the summer transfer window, van Gaal is expected to spend again in the transfer window, and adding another striker could be on the agenda.
Robin van Persie has looked off the pace this season, whilst Radamel Falcao's lingering knee issues remain a problem, with Javier Hernandez out on loan at Real Madrid.
With van Persie, Falcao and Wayne Rooney all over or approaching 30 years old, it would make sense for van Gaal to target a younger, pacier striker.
That's exactly what he's been linked with, after it emerged that Ryan Giggs has been scouting Trabzonspor striker Abdul Majeed Waris.
The 23-year-old, formerly of Forest Green Rovers, hit he headlines with 30 goals in just 63 games with Swedish side BK Hacken, earning a move to Spartak Moscow as a result.
With only one goal in 15 games, he was loaned out to French side Valenciennes last season, bagging nine goals in 16 games before heading off to the World Cup with Ghana.
After his return, the forward joined up with Trabzonspor, where van Gaal's interest seems to have come to the fore. Now, in an exclusive interview with Ghana Soccernet, Waris has admitted his joy at being linked with a January move to Old Trafford.
"Manchester United is a big club and to be linked to them gives goose bumps," said Waris. "I heard it and I read it in the newspapers so it really was a good feeling I must admit."
