Rafael and Fabio da Silva are delighted to have been reunited after spending last season apart and both are enjoying preparations for the new campaign.
While Rafael excelled for the Reds as the team's first-choice right-back, Fabio enjoyed a season gaining further first-team experience on loan at QPR.
The pair are back together on Tour 2013 presented by Aon and relishing the challenge under new manager David Moyes.
"Pre-season is all about fitness and we've all been working hard on tour," Rafael told ManUtd.com. "We had a good summer and a good rest, but we missed playing football!
"Our week in Sydney was very productive. The facilities were great and it's a very nice country. It's been really good to work hard together in training."
Fabio echoed those sentiments and added: "It's great to be back with my brother.
"We have both matured a lot in the last year. My time at QPR has really helped me mature and I also think it helped my brother [for us to be apart]. He had a great year last season.
"As my brother said things have been going well with pre-season. The manager has the same mentality as Sir Alex - he wants to win. He is working hard and so are all the players because we want to win more trophies. Hopefully we can."
