Former Celtic striker Tony Cascarino has told The Irish Sun that Aiden McGeady's career has been nosediving, and hasn't lived up to his potential since leaving Celtic.
McGeady, 29, joined Celtic from Queen's Park at the age of just 15, and he made his way up through the ranks at Celtic Park before he became a first-team star.
With 37 goals and a whopping 83 assists in 252 games for Celtic, McGeady became a wing wizard in the famous green and white hoops, with many touting him for a move to the Premier League.
Instead, McGeady made the shock decision to join Russian side Spartak Moscow in August 2010, and some questioned why the Irish international had made such a bizarre move.
Now, McGeady is back in Britain, having joined Everton from Spartak in January 2014, but he has been a bit-part player for the Toffees, with no Premier League appearances to his name this season.
With his place in the Ireland national team at risk ahead of Euro 2016, McGeady needs to think about a January exit - and a former Celtic star and Irish international has had his say on the winger's career.
Speaking to The Irish Sun, Tony Cascarino says that McGeady's career has been a major disappointment since leaving Celtic, and needs to stop his career from nosediving.
"McGeady is one of football’s enigmas," said Cascarino. "He has so much talent, yet he has not been a regular starter for a team since his Celtic days, before his 2010 move to Spartak Moscow. He has had a bad time with injuries, but even still, the 29-year-old hasn’t even nailed down a first-team berth for Ireland, which is disgraceful considering how much talent he has."
"I’m sure he has made a shed-load of money but in every other respect his career has been a waste of talent. His game is nosediving and he needs to act to turn it around," he added.
A return to Celtic in January may be beneficial, but whether McGeady would be willing to take a huge pay cut to return to his former club remains to be seen, whilst the Bhoys have recently used a transfer policy based on signing young players with potential sell-on value - something McGeady doesn't fit in to.
Yet, having struggled in Europe, it's clear that Celtic still need some proven quality in their side, and they should at least be exploring the possibility of bringing McGeady back to Glasgow during the January transfer window.
