Josemi had struck up a brilliant centre-back pairing with Arnab Mondal, which was the backbone of the Kolkata side that saw them concede a paltry 13 goals in their league campaign.
The former Champions League winning Liverpool left back was deployed centrally and he featured in all of the 17 matches that his side was involved in.
Along with the 35 year old Spaniard, Ofentse Nato, the 25 year old Botswana defensive midfielder too was kept in the ranks.
Nato, who had played for head coach, Antonio Lopez Habas at South African club, Bidvest Wits was a regular feature in the midfield as he looked to break down play and stop opposition attacks.
While Josemi was unattached after leaving Atletico de Kolkata last year, Nato who had a two year deal with parent club, Atletico de Madrid was loaned out to Botswana club, Gaborone United.
Nato was also seen in action as he turned up for the Botswana's 0-0 (7-6 penalty win) against South Africa in an International friendly.
“We have retained Josemi and Nato basis their performance in the last season which helped us immensely in the defence and midfield and I feel they will continue to prove their determination to perform in the next season as well. Their contributions will be essential without any doubt,” said head coach, Habas.
With the dual signing, Atletico have added three foreign players to their contingent after agreeing a deal with Iain Hume, who had turned up for losing finalists Kerala Blasters last time around.
