Speaking at England's training base at PennyHill Park this week, he first of all admitted his excitement to be back involved with his country, and how he is looking forward greatly to Sunday's game.
"With my injury and everything it was pretty frustrating over the Six Nations and missing a big chunk of the season and so I'm itching to get back on the rugby field.
"It's a pretty special place to play at Twickenham against what is a prolific Barbarians squad."
With the Barbarians naming a squad full of stars from around the world, including Gloucester's very own Mike Tindall and Jim Hamilton, Morgan is relishing the battle - especially in the back row.
"I think the back row battles is always something that I look for - I think on Sunday I've got to think about Sergio Parisse, Imanol Harinordoquy and Alessandro Zanni. They're alright, so I guess it'll be easy!!
"It'll be a good weekend, they're always a challenge to play against and I look forward to that".
With Morgan having been heavily tipped to have secured a place to Australia with the British and Irish Lions, he insisted that his focus is firmly on the task in hand with England and the tour to South America.
"For me, it's about playing well for England. If the situation arises to be called up for the Lions, I hope to ready to put my hand up.
"It goes on form, but you've really got to be focused on playing well for England. You can't go looking at possibilities, the ifs, buts and maybes because I think you lose your way a little bit.
"We've got a new squad that's come together and that's about getting on the same page, getting our detail right and playing well as a unit."
With ten international caps already to his name, Morgan feels that in a young squad he has added responsibility, and feels more of a leader as one of the more experienced players within the group.
"I think that I'd like to try and be more of a leader, we talk about it as a group that we need a group of leaders within a team. It's not just about one captain or your vice captain, it's about having a squad of leaders that can play and develop together.
"We always talk about the end goal being the World Cup, so it's progressing towards that. For me, this experience of being able to be more of a leader is a positive one. We've got some young players coming in and this is their first opportunity as well. I've got ten caps so that makes me experienced!"
With this squad providing an opportunity for some of England's young, exciting talent to start to prove themselves on the international stage, Morgan insists that there is still chance for those with the 'X Factor' to flourish.
"The reason that these players are there is because they deserve it. It's about knowing your roles and conforming to the way that we want to play."
