Chelsea player Thorgan Hazard may not yet be as famous as his older brother Eden, but he enjoyed an outstanding time on loan at Belgium club Zulte Waragem, to such an extent that a number of bigger clubs have since been linked with his services.
The younger Hazard is unlikely to walk into the Chelsea first-team squad next season, despite his most recent campaign seeing a return of 17 goals and 20 assists for his loan club.
But those figures prove he is ready for the next step, with Valencia reportedly joining both Liverpool and Everton in showing an interest in the Belgian.
With Chelsea reportedly unsure whether to keep Hazard for the long-term they could opt to part with the play-maker this summer, but there is an alternative, which would see them offer Hazard a new long-term contract before sending him out on loan to see if he really is capable of making it at the highest level.
And there is the dilemma. If Hazard does remain a Chelsea player, the Blues will only know if that is a good decision if they send him to a big club. But in doing so in England they will be directly strengthening a rival – be that Everton, Liverpool or someone else entirely.
A move abroad, possibly to La Liga, will also test him at the highest level but Chelsea will not see what he can do in the Premier League if that happens.
Chelsea showed in the case of Romelu Lukaku that they are happy to send their players to top-flight rivals and Hazard may follow a similar route. But with the top clubs in England getting stronger, Jose Mourinho may be loath to further improve a side who could challenge them for the title next season.
