TURIN (Reuters) - Belgium coach Roberto Martinez believes the weight of responsibility his players felt in their quest for silverware was to blame for their second-half collapse against France in their Nations League semi-final on Thursday. “The second half was a question of emotion, feeling the responsibility of getting to the final,” Martinez told a news conference. “What you have to upload is the commitment and desire of wanting to be there. We all feel as a nation that we are all together hurting, but 12 months from now we have a major tournament. "It is a good moment for us to show resilience, that we want to grow even through this cruel experience.”(Reporting by Alasdair Mackenzie; Editing by Ken Ferris)
