The Lilywhites successfully navigated a tricky group containing the likes of Lazio and Panathinaikos to secure qualifications to the next stage of the Europa League, where they have been drawn to meet French outfit Olympique Lyonnais.
With Spurs also actively challenging for a top four finish in the Premier League, many have cast doubt over the North London club's ability to successfully juggle on both fronts, citing a lack of squad depth as their main weakness.
However, Walker insists that his side will be able to not only secure a top four finish in the Premier League but also lift the Europa League trophy come the end of the season.
"With the squad we have, we can do both," Walker was quoted as saying by the Sun.
"We are quite capable of it.
"We need to go out and attack every game.
"Hopefully that will put us in a good position at the end of the season."
Spurs manager Andre Villas-Boas is no stranger to the Europa League, having won the competition with Porto two seasons ago, and the Portuguese tactician has thus far declared that he is serious about winning it again.
This will come as a relief for Walker, who admits he is eyeing success in the Europa League in a bid to win his first trophy with the club.
"It's massive for me," Walker added.
"I want to win stuff at Tottenham and this tournament is a great opportunity to get a medal.
"We have been good throughout the group stages.
"Things haven't always gone our way but we've hung in there and got the results we needed."
For now, Walker will have to turn his attentions to Premier League as Spurs take on Stoke City in their next fixture.
