Everton midfielder Gareth Barry has urged fans to be patient amid growing disquiet over the club's lack of transfer business.

Midfielder Tom Cleverley and forward Gerard Deulofeu are the Toffees' only acquisitions so far -- and they were both signed in June.

Manager Roberto Martinez is keen to sign a No. 10 and a centre-back but supporters are growing increasingly discontented with the lack of activity to bolster a squad which finished 11th last season.

Chelsea's intent to continue their pursuit of England centre-back John Stones after having two bids -- the last a £26 million offer -- turned down, has only added to the unrest among supporters.

Everton have spent the least of all Premier League clubs this summer but Barry has asked for fans to remain calm.
