Tottenham have missed out with regard to Giannelli Imbula.
Porto paid Marseille £14 million for his signature, tying him to a long-term deal until 2020.
The 22-year-old was compared to Arsenal legend Patrick Vieira by Ligue 1's official website earlier this year, with his powerful and skilful displays for Marseille winning plaudits.
Now if Tottenham want to sign him from Porto next summer - it would be nigh on impossible by their transfer budget, with Porto confirming on their website a release clause of £35 million has been inserted into his newly signed contract.
The figure is one which it is very possible to consider Imbula being worth in a few years, if he continues to flourish and reach his potential - which he will have the opportunity to do in the Champions League with Porto.
Imbula could have become a key presence in the Tottenham side, an imposing midfield partner for Nabil Bentaleb, but now they will have to continue to look elsewhere, as they seek to replace the recently sold Paulinho.
The other side of the coin
French midfielders have not always enjoyed success at Tottenham in recent times. Benjamin Stambouli has failed to make a positive impact on head coach Mauricio Pochettino since signing last summer.
Etienne Capoue was in the French international squad when Spurs signed him in 2013, full of hope he could provide what Imbula will at Porto.
It has not panned out for either, and in that regard it is easier to understand Tottenham's reluctance to try and outbid Porto for the midfielder.
