Kasper Schmeichel was at fault for two of Stuttgart's four goals at Parkhead
At half-time in Celtic's eventual 4-1 Europa League play-off defeat by Stuttgart, the focus was on home goalkeeper Kasper Schmeichel.
"It looks to me as if he is not expecting shots, which is strange for a goalkeeper," former Scotland forward James McFadden said. "He's expecting defenders to stop every shot.
"Teams will be saying there appears to be a weakness to his left-hand side."
The Denmark shot-stopper had been beaten down to his left by a tame Bilal El Khannouss shot for Stuttgart's opening goal, before the on-loan Leicester City man added a second with a free header from seven yards out.
