That is what they did with Dele Alli when he signed from MK Dons.
So could he be the next Dele Alli at Spurs?
Tottenham's Dele Alli celebrates scoring their second goal
Tottenham beat several rival clubs to the signature of teenage Alli in January 2015.
He had emerged as the top young talent in League One, just as Lopes appears to be doing with the Posh right now.
The two are both talented midfield operators, although Lopes appears to be more defensive minded than Alli, but the comparisons are certainly apparent.
Spurs would certainly have an immense talent on their hands if they signed him up – but they would do well to take lessons from their Alli transfer.

If they were to sign him immediately loaning him back to London Road would be a wise decision.
He is still very inexperienced, having only played 21 senior games for the club.
Spurs would certainly be investing in their future with his signature and then loaning him out, as they did with Alli previously.
If they did so, they could have another such talent on their hands.
