I was yes. While we don't know the physical state of the players, he took off the 2 who were causing them most trouble, and put on 2 who did little. Though maybe he thought Thonas would do a job helping at least one of our backs prevent crosses coming in for their big forwards, and Bonne would keep them occupied st the back. Think Albert or Willock would have done the second job better.
Unfortunately, Thomas looks better suited to virtually anything other than playing football.
