Mauricio Pochettino may feel as though he is banging his head against a brick wall at White Hart Lane.
He was acquired by Tottenham Hotspur to bring the eye-catching passing game he had implemented at Southampton with him to north London.
You can, however, only work with the tools you are given, and Spurs do not appear to have the right ones to suit said system.
They have players who are comfortable in possession, plenty of them, but are they right for the tiki-taka approach perfected by Barcelona and replicated by clubs around the world?
It would appear not, with Tottenham unable to swarm all over opponents and push them onto the back foot by pressing high up the field and winning the ball in dangerous areas of the field.
Pochettino will be hoping that this is an issue he can address, with another transfer window almost upon us, and former Spurs and England winger Darren Anderton feels the Argentine has to do something if he is to salvage what has been an frustratingly inconsistent campaign thus far.
He told Sky Sports News: “I think it’s been fairly disappointing, to be honest. When Pochettino got the job, I was excited about the way the team would play this year, with high pressing and playing with high intensity. That hasn’t happened, for me. I don’t think the players he has there can do that.
“Apart from maybe the Everton game, where they pressed high and got at that Everton back four, it’s really been very frustrating, especially in the home games.
“They have played a few games recently and complained about a little bit of tiredness, the Crystal Palace game. I’m not sure I buy into that, it was probably just a poor performance.”
Movement can be expected at Tottenham in the New Year, with Pochettino still working with many of those he inherited from Tim Sherwood over the summer.
Few first-team regulars have been added to the ranks, particularly in the midfield and striking departments, so there is room for improvement.
It is, however, vital that the right type of player is brought in, rather than merely big names, if Spurs are to start embracing the methods of their manager and appease a fan base that has started to air its displeasure.
