The West Ham United players were training on Friday ahead of this weekend’s Premier League game against Swansea City away from home.
Song, who joined West Ham on a season-long loan deal from Barcelona in the summer transfer window, was clearly enjoying training, as the photos below suggest.
Meanwhile, Oxford, who is only 17 years of age and can play as defender or as a defensive midfielder, was looking serious during the session (see photos above and below).
West Ham are eighth in the Premier League table at the moment with 24 points from 16 matches.
The London outfit are five points behind Manchester United, who are currently fourth in the standings and occupy the final Champions League spot.
Meanwhile, Swansea are 17th in the standings at the moment with 14 points from 16 matches, level on points with 18th-place Norwich City.
