Roman Abramovich sprung a surprise visit on Chelsea Women as Emma Hayes' squad toured Jerusalem's historic sites.
The Chelsea owner met the Blues' women stars on Monday, talking at length and posing for pictures with the squad.
Chelsea Women were facing the Israel national side in Tel Aviv on Tuesday evening, with a 13,000 capacity crowd expected at the Ha Moshava Stadium.
Head coach Hayes admitted last term's Women's Champions League semi-finalists were handed a big boost by Abramovich's visit.
"I didn't tell them where we were going," Hayes told PA. "So that was great to surprise them with that. And they were like giggling teenagers when we went into the room.
"But once Millie Bright and Carly Telford went up and asked for pictures, all the girls were asking for individual shots.
"But we spent time not just talking about this game, but the season ahead, our work over the last season and seasons before, and how proud he is of the team and what we do.
"It's such a boost to the players, and especially in Jerusalem, it was a wonderful experience for all of them."
Chelsea remain committed to their Say No to Anti-Semitism campaign, that is heavily backed by owner Abramovich.
"This experience has been immensely spiritual for everyone. It's brought us close together and reinforced the value of life and taking care of each other."
Chelsea spent Sunday morning coaching youngsters from both Israel and Palestine as their pre-season tour of Israel revolves around far more than match preparation.
Stamford Bridge chairman Bruce Buck admitted he has found his first visit to Israel a powerful experience.
"We thought that bringing the women's team to Israel, we wanted to give them some life experiences, some broadening experiences," Buck told PA.
"This is my first visit to Israel, and yesterday was very powerful.
"We're quite happy with our Say No to Anti-Semitism campaign; we're going to continue it and we're hoping we're making an impact.
"We hope we can convince other clubs to launch their own similar projects, and we'll take that one step at a time.
"It's very difficult to measure progress, but we do strongly believe in what we're doing. We believe education is the way to go, and hopefully over time we can make some small contribution to solving the problem."
