The current Newport County manager said that the London outfit is becoming too reliant on the Wales international winger.
"What they don't want to do is become a one-man team and become solely reliant on Gareth. With the acquisitions they are making and the ones they are talking about, I think it could be a stronger squad," he told talkSPORT.
"If they use the money to invest, then they will certainly break into the top three, which would put them in the Champions League.
"They did become a bit predictable in the last few games. They were solely reliant on Gareth to win games. This would really strengthen Spurs for seasons to come."
Bale has been strongly linked with Real Madrid, with the latest reports suggesting that the Spanish outfit have agreed a record £105m fee for his services.
