If a manager wants to improve a team with elite-level aspirations then he will not do so by making mid-level recruitment.
Manchester United manager David Moyes found that out the hard way by acquiring Marouane Fellaini, who played a significant part in Everton's standing but has failed to suitably make the step-up that is required to excel on Stretford.
Since then, the Scot has brought in Juan Mata - a good purchase - while Toni Kroos has also been mentioned as a potential purchase. However, any move for Southampton duo Adam Lallana and Luke Shaw would be a retrograde move - they would not improve the club to the level their fans hope they can return to.
Arsenal boss Arsene Wenger is also making similar errors, if reports are anything to go by. Loic Remy is a great performer - for Newcastle United - but would arguably only replicate what Olivier Giroud has in a Gunners shirt; and that is not good enough for a side who threatened to challenge for the Premier League title this season but, ultimately, threw it away after their victory over local rivals Tottenham Hotspur.
Spurs, meanwhile, are aiming big.
Multiple publications (Express, The Sun) have suggested that Borussia Dortmund manager Jurgen Klopp is a wanted man at White Hart Lane, as the Lilywhite upper brass look to the Bundesliga for their Tim Sherwood replacement.
If Klopp were to ever depart BVB he could have a pick of Champions League competing sides, a competition that Tottenham do not find themselves in next season.
However, they are showing the right ambition in gunning for the staff that can get them to where they aspire to be, unlike United and Arsenal, who appear content to merely sign players of a similar calibre to what they already have.
