In a TV interview after the game, Rodgers was more phlegmatic, pointing out that the assessment of Celtic’s summer business need not begin until the window closes late on Monday, 1 September.

That is still more than two weeks away, so time is on their side.

Bear in mind that, at this stage last season, Auston Trusty, Arne Engels and Luke McCowan had yet to arrive and Adam Idah was still holding a scarf above his head.

“Of course, I would have loved to have had other players in,” Rodgers said on Premier Sports. “We need reinforcements, but I don’t want to keep harping on about it. I don’t need to beg for players that we need.”

So who are those players? Or rather, in what positions are Celtic short?

Bonner talked about the need to identify cover for totemic captain Callum McGregor in midfield and his concerns about a lack of options at left-back to ease the pressure on Tierney.

But his primary concerns lie in the forward areas.

“We still need to find a striker who puts the ball in the back of the net,” he said.

“Johnny Kenny played tonight and he didn’t really have one on target, even though there were lots of crosses. Shin Yamada came on and didn’t have as many opportunities to get on the end of things. Maybe it’s just the way Celtic play.

“Have they got enough in the wide areas? They take off James Forrest and put on Nygren. He doesn’t really play wide; he plays inside. So that’s maybe something else that still has to be answered.”
