Celtic v Juventus: five things Neil Lennon learnt from Champions League last-16 first-leg tie at Parkhead Ambrose declared himself able to play but was at fault for two of the three goals conceded and also missed Celtic's big chance. 2) Celtic lacked the nous Juventus possessed in spades Juventus, as they proved with their WWE tactics in defending set plays, were prepared to win illegally as well as ugly. Celtic's younger team, buoyed by the romance of their victory over Barcelona, could not cope with that cynical approach. They were taken to school by players well versed in the dark arts and lacked the experience or the ability to combat them. 3) Gary Hooper and Victor Wanyama move closer to the exit door Celtic were unable to persuade Hooper and his representatives to sign an extended contract last month, when reaching the quarter-finals of the Champions League seemed entirely possible. Now that Juventus have wrecked those hopes, Hooper is unlikely to be swayed by the prospect of facing two qualifying rounds in the summer before the group stage can be contemplated. He is under contract until the end of next season but Celtic will extract a maximum price for the 25-year-old should they decide to sell him during the next window. While the striker did not enjoy the best of evenings on Tuesday, Wanyama enhanced his reputation with another impressive display, one which is likely to lead to concrete interest from suitors down south. 4) Scott Brown is no playmaker The Celtic and Scotland captain has many fine qualities; he possesses seemingly boundless energy and enthusiasm and is unlikely to be found wanting should on-field conflicts arise. He has drive and determination and attempts to lead by example. What he cannot do, though, is dictate the tempo of contests with his passing, which is one of the weakest aspects of his game and a serious flaw in a central midfielder. Too often on Tuesday the Italians literally bypassed him, with Andrea Pirlo responding to one would-be crunching challenge with a dip of the shoulder and a 40-yard pass which completely altered the flow of the play. It was a reminder, if one were needed, that willingness alone is rarely enough at this level. Celtic played well for long spells on Tuesday. But not well enough. 5) Celtic need Georgios Samaras in Europe Until fairly recently, the Greek striker divided the Celtic support like no other player but he has mad himself indispensable when it comes to any European ambitions the club may harbour. Against Juventus, his height, strength and pace were missed and Hooper, in particular, seemed lost without his partner. The 27-year-old has scored five times in Continental competition this season and, in spite of Kris Commons" best efforts, Celtic appeared lightweight up front without him.
