West Coast's rapid rise up the ladder in 2015 could lead to the Eagles shedding talent, with young midfielder Brant Colledge requesting a trade away from the club despite having a year to run on his contract.

Colledge, who will turn 21 later this month, was restricted to just one senior appearance in 2015, taking his overall tally to three. He was also West Coast's emergency on three occasions this year.

It's understood Colledge and his management informed the Eagles on Wednesday of his desire to leave the club during the trade period, which begins next week. The decision to seek a trade is based on Colledge's desire to have further opportunities at AFL level.

192-centimetre Colledge played 16 games this year for West Coast's WAFL affiliate East Perth, averaging nearly 23 disposals. He polled 19 votes in the Sandover Medal count, more than any other Eagles-listed player.
