The striker picked up a heel problem in the derby against Arsenal on March 16, forcing him out of the Europa League, R16 second leg in Benfica and the Premier League fixtures against Southampton and Liverpool.
It was bad timing for Ade, who has scored 11 goals in 18 appearances since returning to the fold on December 18.
But he's back in training and determined to play his part in a strong end to the campaign.
Has it been a tough time to be sidelined?
Ade: "Yes, it’s been a difficult time. I’ve had an ankle problem, a knee problem and now my heel. I landed awkwardly against Arsenal. I couldn’t get a boot on but now I’m okay. I’m happy to be back. I always want to be out there, but sometimes injuries are part of the game.
"I know we’re going through a tough moment as a team and as a club and we have to keep fighting. There are six games to go and we’ll give everything in those six games."
As you said, we've six games remaining on the Premier League - all tough, but all winnable?
Ade: "You know, if we had 10 games left, I would say let’s try to win them all. So the target is to win all six games. It won’t be easy. We have to give everything, to play with heart, defend well, attack well and believe we can do it.
"We have great players here, we just have to put it together as a team, work for each other and that’s the way we can start winning games."
How important is Monday's match against Sunderland after what happened at Anfield?
Ade: "In football, you are judged day by day, game by game. If we won at Anfield, people would be saying we have a great team, great personality, great team spirit but as we lost, everyone tries to look for reasons, like we’re not together as a team, that sort of thing. That’s how it is.
"If we can win against Sunderland on Monday it will be a different story. I’ve been in this business a while now and know how it works and that’s why I always take it game by game.
"We have to move on from Anfield. You can’t have good days every day. We’ve had good days, now we’re going through a difficult moment. On Monday, you’ll see a Tottenham team determined to win, playing with heart and desire."
