The Teesside club face Brighton and Hove Albion this weekend in a highly-anticipated Championship encounter where one of the duo will seal promotion to the top-flight.
Tied level on points but with a better goal difference, Boro will be promoted of they avoid defeat yet a Seagulls win would see them clinch a top two place and leave Boro in the playoffs.
The home side are favourites to make it, yet Pallister sees a number of weaknesses in their ranks and picks out four positions which will need to be strengthened when asked by reporters for the Independent.
"A right-back, goalkeeper, certainly another midfielder, possibly another striker. It needs to be a really big squad full of quality. There's nothing to stop Boro going out spending £10 - 15 - 20 million on a player anymore,” Pallister explained.
Boro have outspent most clubs in the Championship this season, yet Aitor Karanka’s men have endured a wobble or two and the lack of real quality in squad depth has been evident.
Goalkeeper Dimi Konstantopoulos is in his late thirties and will need to be replaced, while beyond Adam Clayton and Grant Leadbitter there is scope for another top class holding midfielder.
While most supporters can be forgiven for thinking about which Boro players would be well equipped to perform in the top-flight, immediate thoughts simply must go into Saturday’s clash with Brighton.
