Rashford is slowly growing into a valued first-team player at Old Trafford and is currently enjoying his holidays ahead of the 2017-18 season.
However, team-mate Anthony Martial could not let an opportunity to tease the 19-year-old slide when he posted a picture of himself appearing to steer a boat.
Captain Marcus— Anthony Martial (@AnthonyMartial) June 23, 2017
The France international branded the striker "Captain Marcus" to which Rashford responded "Captain Martial" suggesting an inside joke between the two young pretenders.
Both players have a long way to go if they are to have any chance of captaining Man United though, after experiencing uninspiring personal campaigns last term.
Rashford found the net just five times in 35 Premier League appearances, while Martial only managed to score four league goals.
Once they get the playful banter out of the way, they will look to rectify that this term with pre-season and a league opener against West Ham looming on the horizon in August.
