Tottenham Hotspur's lack of quality in reserve could be exposed again tonight.
Andros Townsend appears confident that Tottenham Hotspur have enough strength in depth to compete regardless of who Mauricio Pochettino selects in his team, but his opinion can only be considered misguided.
Pochettino is set to rotate his squad in tonight's FA Cup tie against Burnley and Townsend is sure that whoever is picked will be part of a quality team.
“We’re blessed with a big squad," he told the London Evening Standard. "We have plenty of internationals here and we’ve made a lot of changes for games before, so it won’t be a problem for us whoever the manager picks.”
However, despite Townsend's comments, Tottenham's problems are likely to be exposed rather than solved later this evening.
Although Spurs's starting eleven can be considered one of the strongest in the league, their lack of cover in key areas means that Pochettino cannot implement his strategy to full effect.
The Argentine demands a high-pressing, fast-tempo style of football which requires his players to maintain high levels of energy throughout the match.
It is a demanding philosophy and there must be concerns that many of the squad will become fatigued towards the end of the season.
Spurs struggle to rest many of their key players due to the lack of adequate cover for them in reserve and this is something that will need to be addressed in upcoming transfer windows.
Although it would be foolish to suggest that Tottenham should have players of equal quality to Jan Vertonghen, Christian Eriksen and Harry Kane sat on their substitutes' bench, there should not be such a vast disparity in ability between their regular starters and their deputies.
Spurs have nobody else in the squad that can perform Eriksen's role. The Dane is demanded to be the creative fulcrum of the side and not one player has his poise or class in possession.
Similarly, if Kane is rested their looks a distinct lack of goal-threat in the team. Although the England youth international has scored freely this season, both Roberto Soldado and Emmanuel Adebayor look vastly off the pace.
Elsewhere, Ryan Mason and Nabil Bentaleb have performed an important partnership in the centre of the pitch, with the dynamism of the pair vital to Spurs's success, but none of their replacements seem able to do the same job.
The pair of academy-products were both ruled out of Tottenham's match with Crystal Palace and their loss was clearly felt.
Spurs lacked any pace in midfield, with Benjamin Stambouli and Mousa Dembele both looking sluggish, and it ending up costing them as they slipped to a 2-1 defeat.
Considering the amount of money Spurs have invested in their squad over recent years, their lack of quality in reserve is startling and with Pochettino set to rotate against Burnley tonight he will be hoping that this very obvious deficiency in his squad is not highlighted once again.
