Everton are yet to offer new deals to veteran stars Steven Pienaar, Leon Osman, Tony Hibbert or Darron Gibson, reports the Daily Mail.
Everton endured another disappointing campaign as they finished 11th in the Premier League table.
That is a position many believe is far below where they should be given the quality in the squad and it ultimately cost Roberto Martinez his job.
A busy summer has been anticipated, with the investment from Farhad Moshiri giving Everton additional power in the transfer window while a number of departures have also been predicted.
Pienaar, Osman, Hibbert and Gibson are among those whose futures are uncertain as their contracts are set to expire this summer.
Of the group, Gibson is probably the most likely to be handed a new deal, having managed to get some appearances under his belt this season.
However, with the likes of Tom Davies and Kieran Dowell breaking through this past season, there is every chance the Blues will look to let the older players leave and hand chances to the youngsters.
