The pair made impressive debuts in the 2-0 win at Wolves - combining for the opening goal - before playing a huge part in Sunday's 4-0 win against Liverpool.
"Ade's a great character, gets along with everybody and lifted the spirits in the place," Bale told the Spurs website.
"He can play the ball on the floor, in the air, score goals and that's exactly what we needed.
"He's a good character in the dressing room and we definitely need someone like that. He's a great addition to our squad and hopefully he can keep going.
"Scott's a leader, he shows that on the pitch. He's aggressive, he plays with his heart on his sleeve and he rallies us up before games and gets us motivated.
"They are two great signings for us and I think that's showing on the pitch already."
