Tim Cahill has advised Everton to make a move for former Chelsea striker Diego Costa and believes the Spaniard is well within reach for the Toffees, despite what others may think.

Everton were in superb form at Goodison Park on Sunday as they took Manchester United to the cleaners, running out 4-0 winners in the Premier League clash.

Marco Silva's side have struggled for consistency this season and critics have pointed to the lack of a proven goalscorer in attack.

The Toffees splashed the cash last summer, adding Richarlison from Watford, and Cahill feels there is still big money to spend on Merseyside.

As such he believes Costa, currently at Atletico Madrid, is an attainable target for Everton and would be exactly what is needed up top.

Cahill said on beIN SPORTS Soccer Sunday: "I'd say for Everton, Diego Costa.

"[He is] someone who I think will suit the style, something for the fans.

"Everton are a big spending club.

"You can't look at Everton and say they are a small club.

"Richarlison [£30m] and [Gylfi] Sigurdsson [£50m]. [So] between £30m and £50m, and you say Diego Costa's name and everyone says 'Diego Costa, he won't come to Everton'. 

"Firstly, Everton can pay the wages. Secondly, they can afford him", the Toffees legend added.

Four goals scored against Manchester United have moved Everton on to 50 goals scored in the league so far this season, a total higher than every other side in the division apart from the top six.
