"I dont need to explain why we want 12.5 million when (Layvin) Kurzawa and (Lucas) Digne are valued today at 25 million (£17.7 million). "No one (is) untransferable - but (only) at a fair price."A two-cap Portugal international - he even netted the winner during his nations 1-0 friendly victory over Argentina at Old Trafford last November - Guerreiro is extremely highly rated and is known to bomb forward at every possible occasion, a trait both McClaren and Ian Cathro love in full-backs. Described as a somewhat introverted character, Guerreiro made 33 appearances for Lorient last season, scoring an impressive seven goals from left-back. Throughout his career in all, for both Caen and then Lorient, the 5ft 7in defender has scored eight goals in 108 appearances.
