The Spanish midfielder joined the Red Devils from Chelsea for £37.1million last month and got the opportunity to spend five days with the players and coaching staff in the heat in Dubai over the FA Cup weekend.
"These kind of breaks always help to make the group even stronger and to switch off a bit from the different competitions and the tight schedule," he wrote on his personal blog.
"Personally, these days are good for me to settle even more in the team and share these moments with my team-mates and also, obviously, to train hard and get used to the new working patterns after just three weeks in the club.
"These are long days, with training sessions and events with sponsors; we spend a lot of time together.
"The club thought a few days of work far from Manchester would be good for us, in order to recharge our batteries with a view to the final stage of the season.
"Tomorrow we fly back to Manchester to get ready for our next game in the Premiership (against Crystal Palace on Saturday) and we hope to start a good run of results."
