Am sorry but taking a young hungry striker who scored 15+ goals last season is not a risk. A PL champion CM with a wealth of experience in the leauge is not really a risk is it. And del on loan a barca wonder kid sounds good but ill give you that was a risk yes.
what I think was a risk is leaving it till the last minute to sigh 3 players on deadline day. Although i doubt it's how he wanted it.
personally I think that his biggest risk/mistake is what I've said from day one bringing in kone and getting rid of vic who is younger and his best quality's are holding up balls and laying off to surrounding players which is exactly what we want form our strikers.
But even so we need to remember that as a manager martinez is still learning and growing as a manager at this level but I as a club we are still growing with him and his vision of the club which isn't going to happen in his first season with no money. I think he's been blood brilliant all in all tbh. And am proud to be able to be a fan of a club that is playing attractive football with some damm fine players that is growing to something special.
I think we can all feel this and see it coming on bit by bit each week and i think this is why there is more frustration this year then others we are just not quite there yet. But we soon will be I think.
