Yerry Mina and Dominic Calvert-Lewin began their pre-season preparations on Monday, as the Everton pair underwent a series of fitness tests at USM Finch Farm.
Centre-back Mina and Calvert-Lewin, whose returns were delayed after representing their countries this summer, were joined by Fabian Delph, reporting for his first day at the Club's training base following the England midfielder's arrival from Manchester City.
Delph linked up with his new teammates at Everton's Swiss training camp last week but completed a round of individual testing on his first day's work on Merseyside.

Colombian Mina had a fabulous Copa America tournament, the 24-year-old's team advancing from their group in Brazil without conceding and recording another clean sheet in the last-eight against Chile, only to lose on penalties.
Striker Calvert-Lewin, who started 10 of Everton's final 11 games last season, was part of the England squad which competed at last month's European Under-21 championship.
