How Southampton star's season so far compares to the player he replaced, Luke Shaw, now of Manchester United.
The left-back was overlooked by Roy Hodgson, while right-back Nathaniel Clyne did get the nod, leaving the on loan Chelsea defender perplexed.
He told SkySports: "I'm very disappointed. I've started very well this season, we're second in the league, so I don't know what the criteria is to get in there at the minute."
It was at Southampton last season that the performances of Luke Shaw earned a call-up, and a place in Roy Hodgson's 23-man England squad.
We took a look at the displays of Bertrand this season under Ronald Koeman, statistically, to see how they stacked up with Shaw's under Mauricio Pochettino in 2013/14.
|Season||Passing Accuracy||Won Tackles per game||Interceptions per game||Crossing Accuracy||Effective Clearances per game||Successful Final Third Passes per game|
The pair are relatively evenly matched, displayed by both recorded a crossing accuracy of two per cent, and just two per cent separating their pass completion rate.
Shaw wins almost twice as many tackles per game as Bertrand does, yet that is evened out by the opposite being true by the current Saints star winning almost double the number of interceptions.
The Manchester United star was far more productive in terms of clearances, but Bertrand makes more successful final third passes per game than the player he replaced.
Naturally the evidence to support the case for either is inconclusive, which it itself explains that Bertrand is performing at a similar level to a player who was sold for £30 million.
If one if good enough for England, then it's fair to say the other deserves a look too, and if Bertrand keeps up his form, it won't be long until he does get the opportunity he craves.
