Bruno Fernandes says he will give “everything” to bring “success and trophies” to Manchester United after joining on a five-and-a-half year deal from Sporting Lisbon.
The midfielder, 25, has joined for 55m euros (£47m) but add-ons could increase the overall cost to 80m euros (£67.7m).
Manager Ole Gunnar Solskjaer said the midfielder was a “fantastic addition”.
