On the last day of the season, Tottenham were taught some very harsh lessons by Newcastle.
The Magpies may have been relegated, but Spurs had a lot to learn from them nonetheless.
Now, Mauricio Pochettino would do well to look to Newcastle again, only this time as an example of a transfer policy gone horribly wrong.
Newcastle have opted for a French connection for several years, boasting no less eight players this season from over the water this season just gone.

However, the likes of Moussa Sissoko, Yoan Gouffran, and Sylvain Marveaux have all struggled to perform in the Premier League. Sissoko, in fact, was barely visible at all this campaign until the final day against Spurs, when he appeared motivated solely by a desire to put himself in the shop window.
Spurs have been linked with numerous transfer targets from Ligue 1 this summer, but Pochettino must surely be concerned that they may not be up to scratch.

The one accusation that can really be levelled at Zlatan Ibrahimovic this season has been that he has been playing for Paris Saint-Germain in a league that lacks depth, summed up by the failure of French clubs in the Champions League and Europa League.
With that in mind, Spurs should perhaps think twice before opting for Michy Batshuayi of Marseille, or Lyon's Alexandre Lacazette.
In both cases, they may have to fight off competition from West Ham for their signatures, and the question has to be raised of whether that is worth doing.
Spurs have a bit of a history of signing forwards who have flopped in England, see Roberto Soldado, Grzegorz Rasiak, and Helder Postiga. That record should make them more cautious.
Of course, Lacazette and Batshuayi could turn out to be successes in the Premier League. Pochettino needs to be sure of that, though, as he has a relatively limited transfer kitty of £60million this summer and cannot afford to squander any of it.
The Telegraph are now suggesting Spurs may drop their long-standing interest in Batshuayi in favour of Swiss teenager Breel Embolo.
What Spurs need, however, is a proven Premier League striker, albeit one who is willing to play second fiddle to Harry Kane. Shane Long and Saido Berahino are both viable options, but if they continue to favour Ligue 1, they may find themselves paying well over the odds for a player of dubious quality.
