He was alright last night , fitted nicely into their team kept the ball moving , didn't lose possession but at the same did not have a major impact on the game.
However, that is probably his first competitive game since last season and when you consider this he looked ready to play and didn't seem particularly rusty. I would probably give him a 6.
In the longer term I am far from convinced that he will be a mainstay in our team for years to come but it is unfair to judge just yet as this recent injury will have been a real setback.
On a slightly different note, I thought the Irish midfield was crying out for Gibson last night. The luck of the Irish was never more true than getting a penalty which imo was not a penalty at all. We were struggling to retain possession and kept giving the ball away. Last night the opposition was weak if we play like that against better teams we will be slaughtered. We need to bring our better footballers into the team and if Gibson can stay fit then he must come in.
