Wallace currently plays at MLS side New York City, however two years ago, he plied his trade in the Brazilian top tier. The midfielder played for Sport Recife, and speaking to 'Sky Sports', he has stated that this will help him when Costa Rica play Brazil in the World Cup group stages.
"Being in Brazil taught me a lot of things, not only on the field but off the field," he stated. "From the football perspective, it taught me a lot about the value of possession. They keep hold of the ball more and they attack more. It is also the little things like how the referee manages the games. Everything is that little bit different. It changes your whole game and for me it was a great place to be. It got me to where I am today."
"The people demand a lot of you there and it creates a different dynamic.You feel the pressure week in and week out not only from your team-mates but from the fans."
"Every single time you are on the field over there it is kind of do or die. That is how it should be, of course. But over there you feel it more intensely. There are four teams who come up and four teams who go down every season. The stakes are just different."
At the age of 29, this will be Wallace's first ever World Cup, after he missed out on the action in Brazil in 2014 due to a knee injury. It was a tough blow to miss the tournament, where his nation made it out of a group containing Italy, Uruguay and England, but that's in the past now.
"You know what, I have put that behind me," he stated. "I don't think I would be where I am if I was still holding on to something that happened years ago. We would not be having this conversation. I am happy with where I am now. Everything is going to plan this time around, but the hard work never stops. I have a lot of learning still to do."
