Tottenham midfielder Dele Alli is already undergoing preseason training.
Baldock took to Instagram yesterday to post a picture alongside Alli and his former Spurs team-mate Kyle Walker-Peters at a professional training camp abroad.
Baldock said: "Good week away getting ready for pre-season."
Alli also shared footage of himself at The Campus sports village in Portugal, saying: "The graft doesn't stop."
The pair know each other well from their time together at MK Dons earlier in their careers.
