And my point is that it makes no sense whatsoever. If we wanted to do a package deal, why wait to sign him ?? We would have signed them together if we wanted to do that, but we did not. Now, after Fernandes is already signed, we literally have no obligation to sign him if we don't want to.
There is nothing dodgy here apart from some fictional scenario you have imagined, which makes no sense in reality.
Why would the agent want to have us sign a player we have no interest in, keep in mind that as a youth player there is not going to be a big transfer fee here, and the agent would get nothing in this. Also, Sporting is not some small obscure club that he needs to be desperate to look to transfer the player now. It would be beneficial for the agent to have the player break through at Sporting, sign a contract and then let him move for bigger money than what would be offered currently.
Also, while dodgy deals do exist, they are not as widespread and obvious as you think. This is not the case here certainly. An agent can have multiple players that he represents, he is not going to jeopardize his main player's big deal over something like this. If every agent wanted to do this, we would be flooded with players we don't need nor rate, which is stupid and is very negative for the club itself. There was no great competition to sign Fernandes anyway that we would need try and put some additional benefits to sweeten the deal.
The likely scenario is that we just want to sign this player, and see that we have an opportunity as we have already worked with the agent before, and that could give us an edge in convincing the player to our side.
