On the surface, it would seem like a good exchange; a £25 million striker, who knows Harry Kane inside out, as well as squad space and part of the wage bill freed up.
However, should Tottenham take the deal, it gives them a problem.
That problem falls on their flanks, with Lennon and Townsend being two of the best wingers at the club.
Tottenham haven’t traditionally been a wide team over the past few seasons but with Lennon, they have a quick player with bags of Premier League experience and with Townsend, they have another quick player with bags of potential.
Releasing two very good wide men in exchange for a striker risks making Tottenham slightly predictable in terms of how they play.
Gylfi Sigurdsson showed how difficult it is for a centrally strong player to play out wide for the club before his move to Swansea and therein is the problem.
Tottenham are well stocked in terms of central midfield players, but opposition sides will find them far easier to contain if they are playing with no width.
Berahino’s arrival would be widely praised because he’s one of the most talented English players around.
However, Spurs boss Mauricio Pochettino needs to bear in mind the bigger picture and that means giving himself options in wide areas.
Tottenham dominating the ball in central midfield isn’t always going to be possible and at times they’ll have to counter attack, which is easier for any team that has extremely quick wide men in their side.
There is an argument that Tottenham could use some of the cash they would save from this proposed deal to go out and sign a winger in the January transfer market.
However, finding a player with similar experience and potential to the combination of Lennon and Townsend is going to be difficult.
It’s a tempting deal and one which will leave Spurs with a lot of hard work should they take it.
