I don't think he excelled for half a season. Couple of months maybe.
As for the comparison to Charlie Adam, I can see where you're coming from, but Forbes doesn't have the dig, the engine or the build of Charlie Adam. He also doesn't score the freekicks that Charlie Adam does.
On the dead ball thing, he's missed at least two penalties, don't think he's ever scored a freekick, and I'd say 90% don't even force a save from the 'keeper.
When him and Slane burst onto the scene against Flamurtari, I really wanted them to be good. But I think some folk on here had decided that they'd made it already. Admittedly, Forbes did keep his good form up for the first part of the SPL season aswell, but the tactics were completely suited to his game and when the going got tough, Forbes got going. He is far too slow to command a place in an SPL midfield, has a worse level of stamina than the one that had McGarry slated on here, and is very guilty of picking the wrong pass or shooting when the pass is on.
Like I said, I really hope he comes out this season and proves me wrong as it's always that bit nicer to see the boys that have come through the ranks doing well, but I can't see it happening, I'm afraid.
