ADELAIDE captain Taylor Walker says departing Crows defender Jake Lever has chosen money over success in deciding to join Melbourne. 

Walker also denied reports the Crows were arguing among themselves during half-time of their Grand Final loss to Richmond.

Lever has requested a trade to the Demons on a four-year deal worth a reported $3.2 million so he can be closer to family in Victoria. 

But Walker is adamant money is Lever's main motivation for turning his back on the Crows.

"I think it's him choosing money over success," Walker told Triple M on Tuesday morning. 

"For Jake, I think the difference in money was a lot.

"So if you're driven by money or if you're driven by success, that's a decision you need to make." 

The Crows have qualified for the finals for the past three years, culminating in winning the minor premiership this year but losing the Grand Final. 

In contrast, the Demons have missed the finals for the past 11 seasons, although they narrowly missed out on making the top eight this year. 

Two days after the 48-point loss to the Tigers, Lever called Walker to inform him he would be requesting a trade to the Demons. 

"I didn't have a crack at him, I was pretty honest because I don't like people leaving our footy club," Walker said. 

"I don't think I was arrogant or aggressive towards him.

"I was probably blunt."

The Crows and Demons are yet to agree on a trade for Lever.

The Crows want two first-round picks for the 21-year-old, who played three seasons for the Crows and was named in the 40-man All Australian squad this season. 

However, the Demons are prepared to offer a first-round and a second-round selection.

They have pick No.10 and No.27 in this year's draft, but could offer a future first first-round or second-round selection instead.

Walker disputed a claim from Channel Seven commentator Tim Watson, who said Tigers player Shaun Grigg observed the Crows arguing among themselves during the Grand Final.

"I think it's really healthy that you challenge each other on the field," Walker said. 

"At no point did I think there was an argument. 

"I'll be 100 per cent honest, if I thought there was an argument on the field, I'd say it. 

"I don't think there was any argument and there was not a dust-up at half-time."
