London - This has been a season of unanswered questions, but in north London at least things should become a little clearer after Tottenham Hotspur's trip to Arsenal on Saturday lunchtime. After squandering a two-goal lead to draw with West Ham United last week, there are renewed doubts about Arsenal's mental resolve, while Tottenham's home defeat to Stoke City similar raised questions about their capacity to maintain a run to Champions League qualification.
Spurs striker Robbie Keane, though, is adamant that his side has what it takes.
"You look at the two squads and we are definitely on a par," he said.
"In the last four or five years Arsenal always managed to get ahead of us but if you look now it is even.
"It will be judged at the end of the season but if you look at the bench we have, it is probably a bit stronger than their bench.
"The mentality around the club in previous seasons was that we would be happy to finish fifth or qualify for the UEFA Cup, but there is a different feeling now.
"The players have the feeling that we want to get to the Champions League."
Winger Aaron Lennon is likely to miss out with an ankle injury, and could be replaced by David Bentley, who excelled in Tottenham's 2-0 Carling Cup victory over Everton on Tuesday.
For Arsenal, goalkeeper Lukasz Fabianski comes back into contention after injury.
Having beaten Bolton Wanderers 4-0 in the Carling Cup on Wednesday, Chelsea travel to the north-west face them again in the league on Saturday looking to allay fears about their away form.
"It was a bit of a stroll," Bolton manager Gary Megson admitted, but he expects better at the weekend.
"The venue will be different, the teams will be different and our approach will be different."
Liverpool face another test of their character - they may have beaten Manchester United last week, but five defeats in six games in all competitions is troubling form - away to Fulham, which leaves only the champions United with anything resembling a straightforward fixture.
They are home to Blackburn Rovers, who were struggling even before succumbing to swine flu last weekend.
Manchester City, meanwhile, after three straight draws in the league, travel to Birmingham City, buoyed after their 2-1 win over Sunderland last Saturday.
