Barca centre-back Umtiti took advantage of the free day Valverde gifted to visit his Arsenal friends, who had a match against Tottenham at Emirates Stadium in London.
Umtiti, who is the Juventus target for replacing injured Chiellini, has travelled to London to watch Arsenal vs Tottenham, which ended in 2-2.
It's not the first time Umtiti went to see his Arsenal friends. There are Aubameyang, Lacazette and Guandouzi, with whom he has a very good relationship.
