For the entire match, many of the Spurs players did not show up with their best effort.
There will also be plenty of questions surrounding manager Andre Villas-Boas, whose substitution of Emmanuel Adebayor for Jermain Defoe will be questioned for quite some time.
Here are the player ratings from the disappointing loss at White Hart Lane.
Goalkeeper: Brad Friedel
Friedel kept Tottenham in the match during the first half with two strong saves on Arouna Kone and Shaun Maloney just a few minutes apart.
The American keeper was one of the better players on the pitch on Saturday and was not at fault for the Wigan goal, as he had to move all the way across the goal after making a save that was deflected down to goal scorer Ben Watson.
Friedel will most likely get a rest on Thursday during the club's Europa League match against Maribor,but should be back in the starting 11 for next Sunday's EPL match at Manchester City.
Defenders: Kyle Walker, William Gallas, Steven Caulker, Jan Vertonghen
The back four for Tottenham should be given a lower grade than a C+ but they were saved by the efforts of Vertonghen in attack.
Vertonghen was one of the more active players in a lackluster attack for Spurs all day.
The Belgian showed that his link-up play with Gareth Bale on the left wing is getting better, but he was unable to provide a goal for his club on Saturday.
As for the rest of the back four, they did have a few good moments during the match, but for most of the 90 minutes, they were highly disappointing.
Wigan's forward trio of Kone, Maloney and Franco Di Santo were able to slip behind the defenders and get chances on goal for most of the match.
The defensive unit will have to play much better against Manchester City if they want to come close to winning that match.
Midfielders: Sandro, Tom Huddlestone, Clint Dempsey, Aaron Lennon, Gareth Bale
The midfielders for Spurs also disappointed on Saturday.
Sandro came off in the first half due to injury and Huddlestone was caught defending for most of the second half instead of being a heavy influence in the attack like he was in the first half.
Dempsey and Lennon both were unproductive as they both lacked the final touch when they came close to the net.
Bale was the most productive of the starters in midfield but he did not seem like himself when it came to finishing.
The Welshman put in a ton of effort after Wigan opened the scoring in the 56th minute to score the equalizer for Spurs but in the end he fell short.
The same core in midfield will be asked to start on Thursday as Spurs need a full three points in the Europa League.
Sandro will most likely be replaced by Jake Livermore, while there is a possibility that Gylfi Sigurdsson could start as well.
Forward: Jermain Defoe
Defoe was barely heard from for the 58 minutes he was on the pitch.
Just as the Englishman was hitting a good spell of form, he dropped off immensely on Saturday.
With his lack of a performance against Wigan, it could open the door for Emmanuel Adebayor to start in the near future.
Substitutes: Gylfi Sigurdsson, Emmanuel Adebayor, Tom Carroll
The three substitutes that Villas-Boas used on Saturday did not have a huge impact on the match.
Sigurdsson was forced to come in due to the injury to Sandro in the 23rd minute and only made one or two ventures into the penalty area in attack.
Adebayor replaced Defoe in the 58th minute and he failed to make any type of impact in the quest for an equalizer.
By the time Carroll came on in the 79th minute to make his EPL debut, the fate of Tottenham was close to sealed and he had very little chance to change that fate.
Manager: Andre Villas-Boas
Just as the criticism of AVB was going away, it came right back during and after the loss to Wigan.
Instead of bringing on Adebayor to partner Defoe up front, Villas-Boas decided to take off Defoe, and his decision backfired.
There were also no decisions made by AVB to enforce the lackluster attack, as he brought on Carroll instead of Iago Falque late in the match.
No matter what happens against Maribor on Thursday, he will still be criticized in the media until Spurs come up with a big win.
Luckily for the Portuguese manager, he has the opportunity to do that with Manchester City and Arsenal up ahead on the schedule.
