I'm surprised some of you think he'll play in U23 and get few games for us so if that's case, he would never sign for us, he'll be the first choice at Porto, playing week in week out and able to play in UCL rather than sitting on the bench most of the time like Axel? He will be our rotation alongside with Valencia until the end of the season so we can examine his progress for 18-19 season and if he is ready to be the first choice or we have to sign new RB, Valencia is not going to stay with us next season due to his contract.
