I'm probably going to take pelters for this. I simply don't agree about Eddie & Costa.
Let's start with Costa. I was sat with Leeds60 watching the match. I remember saying that I was disappointed in Costa, as he'd been on for 25 minutes & done nothing of any significance. Leeds60 corrected me, as he had one decent run. OK, so I was wrong. He had ONE good run against a tiring, inexperienced team with his fresh legs and the result was that he produced NOTHING. A bit like Harrison. But of course, being part of the 'played subs who brought victory', he gets plaudits & Harrison gets vilified. For exactly the same end product. Next to nowt. Has it occurred to anyone that it might just have been good work by Barnsley that stymied them, and not their own personal capabilities? Tin hat in place.
Now I suspect a tin hat will be no use for this one, so let me type this from a bunker. So, to start in a Monty Python-ish fashion: 'What did Eddie ever give us in that match', which would no doubt elicit a very smug response of ' a goal and a penalty, muppet!'. And you'd be right to say that. That is ALL he gave us. Did he pull defenders away to free up others? Did he hold up the ball? Did he do anything else that would suggest he could play up front on his own? No. Am I upset? No. That's not what he was signed for. He was signed to score goals. And he does! But we still need someone to do what Bamford does so well. That defence was battle-weary after him battering them (Halme's nose!

), and he knew it. He also knew that goals were coming, hence his histrionics when being substituted. And then Eddie came on, thankfully. So let's examine this goal & penalty. What special 'Eddie' qualities won us each? Well, imo, nothing, other than being in the right place at the right time - like anyone else would have been. His goal was down to the quality of KP's free kick. Quality that had been sadly lacking throughout the match, I might add. Anyone standing where Eddie was could have scored it. And I include Bamford in that. Btw, whilst I'm at it, do I think Eddie would have scored any of Bamford's chances? Probably not. In the first place, I don't think he's the kind of player to get into the situations that Bamford does. Not a criticism - he's just a completely different type of player. Penalty. Was it because it was Eddie? No. Tired defenders, so it could have been anyone with a bit of pace. Nothing special from Eddie. Fabulously received penalty, I might add, but frankly, it could have been anyone. So, my conclusion is that Eddie is very welcome, has a lot of pace & goal-scoring talent, but is NOT a replacement for Bamford. If anyone is, it's Roberts, imo. Of course that could change with Biela's tuition, but it won't be this side of Xmas.
Just finish up by being absolutely clear. Costa & Eddie are both brilliant players and will do wonders for us. I have no doubt about that. But let's not get carried away with the performances you THINK they would have put in whilst sitting on the bench. Bielsa, more than anyone, is perfectly aware of what they bring to the party. HE signed them, remember? Also ask yourself how things would have panned out if the subbings had been reversed.
