[4][6] In 1899, Morris moved to London with his father while his two older brothers stayed in Barcelona and began playing for Hispania AC.

[6] During their time in Hispania, the three Morris brothers joined the ranks of FC Barcelona on two occasions: the first on the occasion of the match against the officers of the British cruise ship HS Calliope on 23 November 1901, where they helped Barça to a 4–0 victory,[6][7] and the second in May of 1902, when they reinforced Barça during its participation in the Copa de la Coronacion, the first national championship disputed in Spain and the forerunner for the Copa del Rey.

[4] After this parenthesis with Barça, the Morris brothers continued to play at Hispania AC until 1903, when the club was dissolved for lack of players, but while Samuel retired due to his advanced age, Miguel and Enrique joined FC Barcelona permanently, playing for the club for two years until 1905, and helping them win the Catalan championship in 1904–05.

[6] In 1903, Morris played three friendly matches between teams made up of the best players in Barcelona, the first at Muntaner on 17 May, the second just four days later on 21 May, and the third on 8 September, scoring once for the Reds in a 3–4 loss to the Whites.

[12] On 8 December 1912, Morris played for a Selection of foreigners who played in Spain (which had the likes of Jack Greenwell, Walter Rositzky, and Alex Steel) in an eventual 2–5 loss to the Catalan national team at the Camp de la Indústria, on the occasion of a benefit match for the Union of Journalists.
