"Man-for-man I don’t think they’re any better than us," Downing said yesterday, ahead of the meeting between the two sides at the weekend.
In this piece we take a look at whether Downing's analysis is correct, by comparing their two teams to create a combined XI.
Goalkeeper: Adrian vs Hugo Lloris
Lloris takes the goalkeeping spot in the team, despite Adrian's good form this season. The West Ham stopper is one of the more underrated players in the Premier League, but Lloris is amongst the finest goalkeepers in world football.
Left-back: Aaron Cresswell vs Danny Rose
The Hammers left-back has been one of the surprise packages in England's top flight this campaign and he looks a better choice than Rose. Cresswell has adapted to Premier League football brilliantly after signing from Ipswich Town, whilst Rose has struggled at times this term.
Centre-back: Winston Reid vs Eric Dier
Dier has the potential to be one of the best centre-backs in England if he continues to progress at his current rate, but he is not as good as Reid as things stand. The pair could be teammates next season, if rumours in the Mirror are to be believed.
Centre-back: James Collins vs Jan Vertonghen
An obvious choice for this spot in the team, with Jan Vertonghen the far superior player.
Right-back: Carl Jenkinson vs Kyle Walker
Tottenham's Kyle Walker has shown how important he is to the side since his return from injury and he looks a better choice than Jenkinson. The Arsenal loanee has done well for the Hammers, but he isn't as complete a defender as Walker.
Left midfield: Stewart Downing vs Christian Eriksen
Downing may have improved considerably this season, but he has never reached the heights Eriksen has throughout his career. The Dane is Tottenham's most talented player and goes straight into this team.
Central midfield: Cheikhou Kouyate vs Nabil Bentaleb
Kouyate has been one of West Ham's player of the season, but Bentaleb's talent is massive and his greater mobility makes him the preferred selection. For a 20-year-old, the Algerian international is staggeringly good and he looks to have the ability to be key for Tottenham for years to come.
Central midfield: Alex Song vs Ryan Mason
Alex Song's greater composure in possession gets him into this team. The West Ham man has made a huge difference to the quality of their build up play and they will be determined to make his loan move a permanent one this summer.
Right midfield: Enner Valencia vs Nacer Chadli
Valencia's pace and power make him an attractive choice, but Chadli has unquestionably been the more productive of the two this campaign. The Dutch winger has seven goals and five assists in 22 Premier League games and he has made huge improvements.
Striker: Andy Carroll vs Harry Kane
Harry Kane's rise to prominence has been rapid and he simply has to be included in the team. The striker has hit the back of the net with impressive regularity this season, whilst Andy Carroll's injury problems have persisted.
Striker: Diafra Sakho vs Emmanuel Adebayor
Sakho looks capable of leading West Ham's attacking unit for years to come. Clinical, powerful and quick he has all the makings of an excellent Premier League striker and his goal return has been hugely impressive.
Managers: Sam Allardyce vs Mauricio Pochettino
Allardyce may have improved West Ham this campaign, but he is nowhere near as forward-thinking in his approach as Pochettino. The Argentine has transformed Spurs already and their future under his guidance looks very exciting.
Overall: West Ham 4 - 8 Tottenham Hotspur
It is hard not to think that Downing's comments were hyperbolic, as Tottenham's team looks superior. Although West Ham do posses some quality players, they do not have the depth that Spurs do and it is no surprise that they are looking up at their London rivals this season.
