Atalanta’s Champions League wealth make Celtic look small, and Brendan Rodgers is haunted by the decision he made to let Atalanta go.

The £11 million Celtic paid for Arne Engels from Augsburg was a lot of money, but the amount they will have to spend to beat Atalanta is out of this world.

The Scottish Premiership winners have already learned the hard way how bad they are when they play the big teams in the winners League. In Germany, Borussia Dortmund beat Brendan Rodgers’ team. However, Celtic faces another bad set of numbers when they play the winners of the Europa League, whose team works more than twice as much as Celtic’s.

Rodgers will also have to deal with Ademola Lookman, who was one of the Celtic players he wishes he hadn’t bought. The winger was amazing in the Europa League Final. He scored a stunning hat-trick that beat Bayer Leverkusen and helped the Serie A team win their first big trophy since 1963.

Lee Congerton, who used to be in charge of recruiting at Parkhead, said that the manager was desperate to bring him to the east end of Glasgow when he was at Celtic for the first time. Before his £12.5 million move to Atalanta, Rodgers was unable to make the loan move from RB Leipzig permanent. However, he did get his man while he was in charge at Leicester City. The player is now worth more than £40m.

He said after Lookman’s heroics in Europa: “When he knew we couldn’t take him, he took him to Atalanta, and he has done absolutely brilliant there. I am so happy with the goals he scored!” Most of all the second and third ones.

“He scored some huge goals for me at Leicester. One of them was the game-winning goal at home against Liverpool; it was a great individual goal.” We at Leicester were only sad that we couldn’t sign any players that summer, even though we could have bought him for £14 million at the end of that season.
