The midfielder had been invited to make his own introduction after agreeing a two-year contract in January and described himself as an "amazing player", only to be made to wait almost four months before starting his first game. That experience lasted only until half-time.
His declaration might have been forgiven given it came from a player compelled to articulate his own worth following a year with Celtic that offered only a sheltered existence, but it still seemed a flawed translation last season. It is only now that Ibrahim's actions have spoken louder; the Nigernian having started the last two matches under Allan Johnston, using the space behind Kilmarnock's strikers to exhibit his most arresting work.
A routine of reserve fixtures and the odd substitute appearance since moving to Scotland in January last year has been interrupted by just one full competitive match - a Scottish Cup tie in December which ended with Celtic drawing at home to Arbroath - but that has done little to disturb his sangfroid. The 22-year-old has settled, too, under a manager who has sought to encourage the sense of imagination which has previously held the attention of coaches at Sporting Lisbon, PSV Eindhoven and Celtic.
"He's been brilliant, creative, and some of his skill is unbelievable to watch," said Johnston, whose side face Hibernian tomorrow. "We are just trying to work on his end product and add goals to his game. He's started to put some crosses in and he's always trying to look for that pass in behind which strikers love. But he's not a spare player; he works hard defensively as well. He is just getting his fitness as he has not played a lot for a while. He is just now getting used to being a first-team regular rather than a sub. He's getting stronger and stronger."
Even so, such an assessment comes with a but. It is one so big that Hibs would be lying if they suggested that they did not care for it. Kris Boyd is suspended tomorrow after the striker was sent off against St Mirren for violent conduct, leaving Kilmarnock to make do without the only player to have scored for them this season. "But we have options," said Johnston. "[Paul Hefferan] has been unlucky; he is getting in the right areas and he is a goalscorer. Then you've got the likes of William Gros and Mark Stewart. Hibs have good players, but so do we."
