Norwich manager Chris Hughton is under growing pressure due to the Canaries poor recent form.
But his case was not helped by Canaries' Chief Executive David McNally who publicly questioned the tactics used against Fulham in the FA Cup replay defeat.
John Giles joined us for Thursday Night Football and defended Hughton and thinks McNally overstepped his mark.
"Unfortunately, it's the way of the game. A lot of these directors like to be high profile and it's very easy to be wise after a match. Chris Hughton is a gentleman and this clown (McNally) should keep his mouth shut and let Chris get on with the job. And if he doesn't let [Hughton] get on with the job, he should sack Chris and get in himself and do it."
Meanwhile, back in 2011 Nemanja Matic left Chelsea for Benfica for less than €6 million, yet has been brought back to Stamford Bridge for €25 million.
Similarly, Manchester United are interested in bringing Juventus' starlet Paul Pogba back to Old Trafford 18 months after his sale.
That got us thinking: Why do some clubs fail to spot the potential of a player until it is too late?
John thinks there is a simple explanation.
"It wasn't Mourinho who sold him to Portugal. It was Ancelotti. So you have two managers who have two different opinions of the player. That's not usual. I would've been close philosophically to Norman Hunter and Nobby Stiles but we didn't always agree on the value of players. Every manager has a different opinion of players. Mourinho obviously thinks more of him then Ancelotti did. He mus think he can get something from the player," said John, who then touched on why Chelsea stockpile young players like Romelu Lukaku and then loan them out (indeed there are six Chelsea youngsters at Vitesse Arnhem).
"If you look at most of those players, they're quite young. They obviously see the potential and indeed some of them are very good players. But Chelsea need instant success. They buy a lot of those players for investment and I think a lot of them will come good."
John then previewed Chelsea's clash against Manchester United where "everything that could have gone wrong, has gone wrong."
But he also looked back at his own hero, Bobby Collins. The former Leeds United, Everton, Celtic and Shamrock Rovers player passed away this week after a long battle with Alzheimer's.
"He was a great player. He was even smaller than me, believe it or not. He was 10 years older than me and he was a hero of mine when I was a kid because the Scottish league used to come over every two years to play the League of Ireland and Bobby was in that team, most times," said John.
"He made his debut for Celtic at 17 and had a 10-year career there before he went to Everton for five years and then Don Revie bought him and that was the big signing for Don. Bobby Collins started off the great team at Leeds and one of the reasons I went there was because Bobby was there, and I learned lots from him. His influence stayed there after he left."
