NAC Breda chief Hans Smulders was in England this week for talks with Manchester City.
NAC and City enjoy a partnership agreement, which has seen the Premier League giants place young players at the Dutch outfit.
Smulders traveled to England with the hope of taking a goalkeeper on-loan. Angus Gunn and Ian Lawlor were discussed.
"For those players, there is a lot of interest and there is too much uncertainty about what the new coach Josep Guardiola will want.
"I want all the keepers at the first training session of Sunday, June 26," Smulders told BN / De Stem.
Divine Naah isn't expected to extend his loan into next season, while there is also uncertainty around Turkish striker Enes Unal.
Smulders expects more clarity from City in a fortnight's time.
