Martin O'Neill's position at Celtic is under scrutiny after a string of disappointing results. The 74-year-old manager has said he will reflect on the games during the international break, following back-to-back defeats by Rangers and a home loss to Ferencvaros in the Europa League. Celtic had also suffered a shock Champions League collapse to LASK in August, with a 4-0 aggregate lead surrendered.
O'Neill, who was made permanent manager for a second time in the summer, has a reputation for turning teams around. However, Lambert believes the players need to take responsibility for their performances, rather than relying on the manager to solve their problems. The former Ipswich Town and Norwich City manager was critical of individual performances in the defeats by Rangers and the remarks of defender Cameron Carter-Vickers.
Lambert insists O'Neill is Celtic's best manager since Jock Stein, but would not be surprised if he left. He believes O'Neill has enough credit in the bank to walk away, citing the fact that people were once calling for a statue to be erected in his honour. If O'Neill does decide to leave, it would not be a surprise to Lambert, who thinks the manager has the option to go if that's what's on his mind.
O'Neill has a big decision to make about his future at Celtic, with the club two points clear at the top of the Scottish Premiership.
