“It's been very hectic,” he said at Tuesday’s pre-match press conference before the playoff round first-leg in Rotterdam.
“I had already prepared the training for Feyenoord under-21s on Monday evening when I got a late call asking if I could come to the stadium. From there, it all went quickly, I had to switch quickly.”
He has had a single training session ahead of Wednesday’s clash at De Kuip and stuck to the battle plans Priske put together before his firing.
“The preparation had already started, so I sat down to see where we could still make gains and how we could approach it. We are going to implement the plan that was there. I am not going to change everything at the last minute. If you do that, you create further unrest and don't want that."
Although a member of staff at Feyenoord since the start of the season, the 44-year-old Bosschaart had not previously worked with the first team but rather the juniors.
“I don't know the squad at all but I’ve encountered a group of players that are eager. We trained well, it was focused, there was a lot of fun in it," he added.
Besides the disruption in leadership, Feyenoord have to contend with a raft of injuries and will be without goalkeeper Justin Bijlow, defenders Jordan Lotomba, Bart Nieuwkoop and Gernot Trauner and midfielders Ramiz Zerrouki and Chris-Kevin Nadje. The availability of midfielder Hwang In-beom and defender Facundo Gonzalez is still uncertain, added Bosschaart.
Danish-born Priske signed a three-year contract in June last year when he replaced Arne Slot, who left to take charge at Liverpool. He had been under pressure in recent weeks after a string of poor results as Feyenoord sit fifth in the Dutch standings.
