The legendary Frenchman has questioned how strong some Tottenham Hotspur youngsters are upstairs.
Speaking on Sky Sports, Thierry Henry has suggested that England captain Wayne Rooney will be key for the Three Lions at Euro 2016, adding that some of Tottenham Hotspur's young players are "mentally weak".
Manager Roy Hodsgon has chosen five Spurs players in his 23-man squad for this summer's tournament in France, with three of those - Eric Dier, Dele Alli and Harry Kane - under the age of 23.
All three Tottenham stars enjoyed wonderful 2015-16 campaigns, with Kane picking up the Premier League golden boot with 25 goals, while Dier and Alli emerged as some of the division's most promising young midfielders.
Tottenham's title charge fizzled out in the final weeks of the season after drawing 2-2 with Chelsea, having led 2-0, before defeats by Southampton and Newcastle United - the latter of which being a 5-1 demolition on the final day - capped a miserable end to an overall excellent season.
"Wayne Rooney is going to be key, to be in and around those youngsters," said the Arsenal legend to Sky Sports.
"We saw with Tottenham recently that some of their youngsters can be mentally weak sometimes."
Henry may have a point. It seems as though Spurs' season unravelled at the worst possible time, culminating in a failure to finish above Arsenal in the end, but an experienced outfield head amid the youthful exuberance may have seen Mauricio Pochettino's side finish the season with a little bit more pride.
That being said, all three, along with Kyle Walker and Danny Rose of course, may have prominent roles at Euro 2016 and such an experience will only benefit Tottenham next term.
