Los Ticos, who drew with the Three Lions at Brazil 2014 en route to the quarter-finals, will take on Gareth Southgate's charges in a friendly at Elland Road on Thursday.
Ramirez's side will wrap up their pre-tournament preparations against Belgium on Monday, while England will have no more warm-up games ahead of their Group G opener against Tunisia.
"England have a very good squad at the moment," the 53-year-old told Sky Sports News. "It's a very physical squad. They have a lot of great characteristics.
"Their combination play, their defence is very good. They often like to trick the attackers. They are also a very modern squad and one that has a lot of hope.
"England are one of many sides - Germany, Brazil, Spain, even France, who all have a lot of potential at this tournament."
England, who last won the World Cup in 1966, are currently 13th in the FIFA World Rankings.
