Mauricio Pochettino led Tottenham Hotspur to a third place finish in the Premier League and a place in next season's Champions League. Despite their impressive campaign, a poor finish to the season cost them their shot at the title and they fell behind fierce rivals Arsenal.
The former Southampton boss implemented his renowned high intensity pressing game, and with the youngest squad in the Premier League Spurs were firmly in contention for their first league title since 1961.
The one main criticism of the Argentine's management style has been how his teams seem to run out of energy in the final stages of the season. He is not an advocate of squad rotation, and fielding the same starting XI eventually caught up with the North London club as they looked jaded in their final four games and took just two points from those outings.
Although Spurs have been accustomed to the challenges of European competition in the Europa League, the Champions League next season will represent an entirely different examination. The games will be more intense and the opposition will be of a far higher standard.
With this in mind, it will be vitally important that Pochettino makes at least two smart acquisitions during the summer.
In Harry Kane, Tottenham have arguably the best striker in the Premier League. His 25 goals helped them finish as high as they did, as he competed in every single league game for Spurs. It must surely be a high priority for Pochettino to bring in another striker, not just as a back-up for Kane, but someone who can be rotated with the England striker, and maybe even play alongside him.
For all of Spurs' strengths, they are far too one-dimensional at times, and having another world-class striker would enable them to play a 4-4-2, and give the opposition something different to think about. The difficulty will be in finding a striker of that pedigree, but with Champions League football on offer at White Hart Lane now, they have every chance of attracting the world's best players.
Another important issue for Pochettino to address will be the form of Christian Eriksen. On his day he is one of the best attacking play-makers in world football, but he seems to have a run of games where he goes missing, and looks entirely disinterested.
The Argentine must figure out how to get the best out of his Danish star on a more consistent basis, and that may entail reducing his playing time to ensure he is fresh for the run-in.
To be able to rest a player of Eriksen's magnitude, however, would require having someone of a similar standard to deputise in his absence. Erik Lamela has improved over the past year, but is still some way off from being the finished article. Tottenham are sure to have a healthy transfer budget, what with the riches of the new Premier League TV deal combined with Champions League money, and Pochettino should move for an attacking midfielder who can emulate the effect that Eriksen has on his side.
If the Spurs boss can make these two vital additions to his squad, there will be no reason his Tottenham side cannot challenge for the title again next season, and bring top flight glory back to White hart Lane for the first time in over 50 years.
