Tottenham vs Southampton prediction (Over/Under)

Home team Tottenham is 2nd place and they lost chance to win trophy this season in PL. Now I think that they aren't too much interested for this game, so I expect an low-scoring game. Away team Southampton is 7th place. In last 5 games they have 2 times played under 2.5 goals. In their games come average of 2.55 goals per game. Both teams are very defensive, and in PL often come very little number of goals, so I bet on under 2.5 goals. I looked here on history of results when played these two teams each other, and I noticed that in last 14 games their total has gone under 2.5 goals in 8 games.
