Ramirez joined Premier League club Everton from Spanish side Malaga in the summer transfer window.
The former Barcelona forward has struggled to make an impact at Goodison Park - he has not scored a single goal or provided one assist in 217 minutes of Premier League football so far this campaign.
Former Chelsea striker Cascarino has stated that Ramirez has been average for Everton.
The former Republic of Ireland international has also give his verdict on another Everton summer signing Nikola Vlasic.
Cascarino wrote about Ramirez in The Times while giving him 4 out of 10: “It was always going to be hard trying to replace Romelu Lukaku’s goals but Sandro has looked average and has not done enough to be given a long spell in the side. Dominic Calvert-Lewin has replaced him in the pecking order.”
“Only 20, so we can’t be too critical but I’ve seen him give the ball away so often,” Cascarino wrote about Vlasic in The Times while giving him 5 out of 10. “He has not produced any real moments of magic so I just hope that his confidence doesn’t suffer.”
Regarding a replacement for Ronald Koeman at Everton, Cascarino said on the Weekend Sports Breakfast show on talkSPORT on Sunday morning (08:24am, October 22, 2017): “If I was looking at a manager’s job today and looking at the way Everton play, I would want to change their direction.
“I think they need to be a little bit more adventurous, a little bit more pace and energy in their team. I think Silva at Watford would be a great candidate for Everton.”
