Eto'o's positioning and ability to finish impressed Stones in the 1-1 draw in their Europa League game against Krasnodar.
The former Chelsea striker came off the bench to latch on to Leighton Baines' cross with less than 10 minutes to go to ensure Everton remained unbeaten in the competition, sending them top of their group.
Stones told the Liverpool Echo: “Bainsey’s ball was unbelievable but great strikers take up great positions. Samuel did that and he provided the perfect finish to a brilliant ball. I’m happy for him."
Eto'o has so far scored twice for Roberto Martinez's side having signed for a free transfer, following his release by Chelsea at the end of last season.
The forward was also said to have caught the attentions of Merseyside rivals Liverpool in the summer but they opted for Mario Balotelli instead.
So far he hasn't been used regularly from the start with Romelu Lukaku and Steven Naismith getting the nod from Roberto Martinez, whilst Eto'o seems to be making more of an impression off the bench. However, with the fixtures coming thick and fast after this international break, he may see more game time for the Toffees this season.
There were times last season when Everton lacked that bit of quality in the final third in certain games. Though they were impressive overall in the campaign, one can't help but feel that in certain games they just needed an older, experienced head in the final third of the field to put the ball in the back of the net.
One example would be a game against Chelsea when Eto'o was at the Stamford Bridge season. Everton had a lot of the play but just couldn't take an opportunity and ended up losing the game in the closing stages.
Now they have that bit of quality available to them, and there's likely to be even more goals from their summer signing.
