Tottenham must avoid Liverpool's transfer mistakes.

After a longer wait than they would have hoped, Tottenham Hotspur are back in the Champions League next season.
It is more than five years since their last time in the competition, and fans will be desperately hoping there is not a similar gap until they next qualify.
Vital to doing this is their transfer market activity, and not repeating the errors made by a side in a similar situation two years.
Liverpool had experienced a similarly long absence from the Champions League before they qualified for the 2014/15 competition.
They bowed out in the group stages, and have not been near qualifying since, with consecutively poor Premier League campaigns.
While the Reds can rightly point to losing Luis Suarez as critical in their 'demise' over this period, they have spent the entirety of the £78 million fee they received for the Uruguayan, and then some.
The problem was for Liverpool that they did not seize the moment, and in a crucial transfer window in 2014, continued to spend like a Europa League side.
Rickie Lambert for England
Players brought in included Rickie Lambert, Adam Lallana, Dejan Lovren, Lazar Markovic and Emre Can, all of who they could have attracted without Champions League football.
It's early days for Tottenham this summer, but they need to ensure the players they bring in, raise the quality of the squad rather than adding players of a similar standard to what they already have - and sign players who are proven in the Champions League.
This summer Manchester United are doing the opposite; they are in the Europa League, but buying Champions League standard players like Zlatan Ibrahimovic and Henrikh Mkhitaryan.
Jose Mourinho's Red Devils will be hoping to swap situations with Tottenham next summer, and if the North London side do not buy effectively this summer, as Liverpool found to their cost two years ago, they could live to regret it.
