The Mali international joined Antonio Conte’s side earlier in the window after impressing with Graham Potter’s Brighton over the past two seasons.
Bissouma was linked with a number of clubs including Manchester United, Liverpool, Newcastle and Arsenal but opted for Spurs, who will also compete in the Champions League next season.
“It’s a good deal,” Murphy said on talkSPORT. “I just think about his potential and his athleticism. I think every part of his game is good.
“I think maybe his lack of goals maybe [why others didn’t bid for him]. Also, the other midfielders. If we talk about Liverpool, Chelsea and Man City, they are not in trouble.”
Murphy also felt that Bissouma made the right call by selecting Antonio Conte’s Spurs ahead of Erik ten Hag’s Man United.
“You’d rather go to Tottenham, wouldn’t you?” joked the former Liverpool and Spurs midfielder.
