The Cameroon international – who has starred for his nation at the World Cup already – is due to be out on contract at Loftus Road soon after spending a season away on loan at Sevilla, and is expected to opt against extending his stay in London.
After a difficult first season at Loftus Road, Mbia rediscovered his form in Spain last term, helping his adopted side to Europa League glory and a respectable La Liga finish.
Talk of an extended stay at the Ramon Sanchez Pizjuan has been rife, but both Everton and Liverpool are readying contract offers for the 28-year-old.
The Merseyside rivals have both been impressed by Mbia’s development over the course of the past few months, and could well present him with a one-year deal and another shot at life in the Premier League.
Liverpool are thought to be narrowly ahead of their enemies due to being in the Champions League, however Everton are able to present the African star with a more realistic chance of first-team action.
Both clubs will be able to out-do Sevilla in terms of salary for the player, which could be a big factor in the outcome of negotiations.
