The future of David Luiz at Arsenal is uncertain as the club has yet to trigger an extension to his contract that will otherwise expire this summer.

Luiz left Chelsea last summer for £8 million on an initial one-year deal with an option for a second season.

Mikel Arteta would like to retain Luiz, but the decision on his contract appears to be an indicator of Arsenal's financial pressures.

Arsenal are the only club in the league to agree a wage cut with their players as opposed to a deferral -- 12.5% for 12 months.
