The striker did not start in the 3-2 win over Burnley but came on for the final 20 minutes.
"But generally I think it's connected. So he finished the game with cramps, really in the limit. That's why we protected Ben from the penalties,” he told the media.
“And today was that reason also, because Sesko is also a striker, he's an international striker. But I was thinking that Ben, during the pre-season, he didn't do 90 minutes. And he did that, even against a 4 division team, he did that on Wednesday.
"And with the problem of Cunha, you don't know if that full game in the middle of the week has something to do with the injury today.
“With the problem with Mason Mount, I was not risking another player, not knowing if they are able to play so many minutes.
“So everything was connected. The penalty, the game on Wednesday, and the number of minutes that I was thinking to put Ben today."
