Keane everytime for me. There is no doubt the God like Gloss that Keane had disappeared a little due to the way in which he left the club and also the honest comments he has made since have not done himself any favours with the fans. Some of his shocking tackles lost him a few fans also. If Keane had always just said what the fans wanted to hear like some lick ass players do then he would be up there with Cantona as our greatest ever player. Fergie says he was the most influential player to play under him. He was not injured half as much as Robson. Bossed games probably a little more than Robson did, was more of aleader than Robson and equally had an eye for a goal like Robson.
In saying that though you cant really say one was better than the other. Its a bit like deciding which of Giggs, Best and Ronaldo was the best winger!! Or whrther Vidic was better than Stam!! You cant have a definite answer.
A midfield of Robson and Keane with Scholes a little forward would simply rape other rival teams of today though!
I don't really want to get into a who is better debate as I can see both sides of the argument. I've never brought the Robbo was clearly better than Keane viewpoint, although he is my preference. Robbo was clearly more of a goalscorer than Keane though and had almost double the goals in his United career and was also often paired with a more attacking player in Whiteside, so it's not as if he had more freedom.
For the goals, Robbo's record in big games was ridiciliously good. For example,
(1) He scored in every FA cup semi final appearance he ever made bar the replay against Oldham. That's 5 goals in 6 games including replays and our semis under Big Ron and then Fergie were always crackers and difficult matches.
(2). He scored in two FA cup finals including a double against Brighton. Should have been three in 94.
(3). I can recall 7 goals against the dippers including two doubles and there would probably be more. That would be 2 in 83 Charity shield, two in the Anfield 3-3, one in both FA cup semi games 85 and the first goal at Anfield when Albiston got the winner. There would probably have been more.
His goal record for England as well is very good. 26 in 90 caps again normaly as the more defensive player of the two in midfield.
Not forgetting the two against Barcelona in the CWC. For a central midfielder who played in a 4-4-2 often as the more conservative player than really is very good.
Only other thing I want a mention is the thing with injuries. If we look over Keane's and Robson's appearances there is very little difference. The truth is Robbo is not as injury prone as alot say in retrospect and Keane picked up more injuries than people tend to remember.
Keane played 480 games for United and scored 51 goals over 12 seasons.
Robson played 437 games for United and scored 99 goals over 13 seasons.
Bearing in mind Keane played in the Fergie era which means constant CL football and was always a first team regular, the difference is not to big. Robbo really was a bit part player in his last two years(abit of a token captain like Gary Nev) at the club when his injury problems were probably worse than ever as well and was below McClair and Keane with Ince the main man.
