Liverpool lacked their usual intensity in Sunday's surprise 2-0 defeat at Newcastle because Jurgen Klopp did not pick a team that could implement his gameplan.
With Newcastle in such poor form and so nervy, on top of the way his side have been counter-attacking so well of late, I thought beforehand that it would be a game that would play into Klopp's hands.
But the Reds were never on the front foot high up the pitch in the same way they were against, say, Manchester City when they won 4-1 at the Etihad Stadium last month.
In that game Liverpool's forwards were putting City's centre-halves and full-backs under constant pressure and setting traps for them whenever they were on the ball.
Against Newcastle, in contrast, they allowed the home team to slowly grow into the game and the Magpies went on to win it convincingly.
The Magpies were the first team to run further and make more sprints than Liverpool in a Premier League game since Klopp took charge, but matching the Reds' work-rate was not the only reason they won.
'Liverpool lacked intensity up front'
Liverpool's basic stats against Newcastle - their total distance covered and number of sprints - were typical of the kind of figures we have seen in some of their impressive wins under Klopp, but something was clearly missing from their performance, and it started up front.
|Liverpool in the Premier League under Klopp|
|Opposition||Result||Distance covered (km)||Sprints|
|Tottenham (a)||D 0-0||113.5||621|
|Southampton (h)||D 1-1||114.5||559|
|Chelsea (a)||W 3-1||115.1||497|
|C Palace (h)||L 1-2||110.9||527|
|Man City (a)||W 4-1||117.4||625|
|Swansea (h)||W 1-0||108.9||542|
|Newcastle (a)||L 0-2||116.5||579|
Klopp clearly had a plan, and a reason, for going with Christian Benteke to lead his attack, as opposed to the front three he had against City when he did not field a recognised striker.
That was always going to mean a drop in the amount of high intensity pressing his team were able to do from the front, because Benteke is not really that kind of player.
Take Benteke out and replace him with another attacking midfielder and you are automatically going to get more intensity high up the pitch.
There was another significant difference in midfield at St James' Park, with Emre Can missing because of suspension.
That meant Klopp had a midfield of Joe Allen and Lucas Leiva, who are both more like holding players, compared to Can, who is far more dynamic and operates box-to-box.
I am not saying Benteke - or Allen and Lucas - were totally to blame for Liverpool's defeat but together they were contributing factors, and I think Klopp got his team wrong this time.

'It will take 8-12 months to apply Klopp's stamp'
Sunday's defeat showed Klopp is still trying to work out the strengths and weaknesses of the players in his squad, and finding out who can fit into his gameplan.
He made six changes from Wednesday's 6-1 Capital One Cup win at Southampton, and he is obviously giving all of his players an opportunity, which is a positive thing. I think the reason he did not seem too down after losing to Newcastle was that he realises it is part of the process.
It will probably be about eight to 12 months, and at least a couple of transfer windows, before he really puts a stamp on this team.
I was talking to a number of Liverpool fans before the Newcastle game and their feelings seem to change all the time about what they can achieve this season - one week they are a work in progress, the next they are back in the big time.
It is too soon to get carried away. There have been some really encouraging signs and glimpses of what Klopp is capable of but there have also been blips - like Sunday - where you are reminded he is only two months into the job.
