Is this Pochettino's biggest decision against Manchester United?

White Hart Lane

Mauricio Pochettino might have a big decision for the visit of Manchester United.

Winger Erik Lamela trained this week following a calf injury, but it remains to be seen if he is fit enough to start against Manchester United on Sunday. If not, it leaves manager Mauricio Pochettino with a choice between Son Heung-min and Nacer Chadli - and he must go with the latter this weekend.

Son was given the nod in last Saturday's 1-1 draw at Liverpool and overall looked more of a hindrance than a help to the Spurs cause. But with the biggest prize in English football still at stake, Pochettino cannot make the same mistake twice.

Chadli, who replaced him after 66 minutes, did look slightly better than Son at Anfield, and if Lamela is not fit enough then the Belgian simply has to start.

The South Korean, a summer signing from Bayer Leverkusen, may prove a wonderful signing in seasons to come, but Chadli, signed during Andre Villas-Boas's reign in 2013, just has that bit more Premier League pedigree at the moment - and his 11 league goals last season prove it.

 

By virtue of the fact he wasn't a Pochettino signing, the 26-year-old may also feel like he has something to prove. Chadli, who has started just 10 of his 23 league appearances this season, might be playing for his future at White Hart Lane - Son will almost certainly be there next term - and that insecurity could well spark a strong showing from him on the big stage.

Pochettino has another decision to make regarding Kevin Wimmer as Jan Vertonghen looks set to return to the squad, but that one is far easier considering the Belgian defender has not kicked a ball since January - not to mention the fact that Wimmer has been a superb deputy overall.

Premier League titles are won and lost based on big decisions at crucial times of the season, and second-placed Tottenham might be as many as 10 points behind leaders Leicester City - who visit Sunderland in the earlier game - by kickoff at White Hart Lane.

Given what is at stake, there is simply no margin for error in Pochettino's team selection, and if it comes down to a decision between Son and Chadli then it must be the Belgian this time.
