Newcastle 2-0 Arsenal: Mikel Arteta admits Newcastle deserved win "by a mile"
Arsenal do not deserve to qualify for the Champions League on the basis of their performance in Monday's 2-0 defeat at Newcastle, says Granit Xhaka.
The midfielder felt his side's display showed they could not handle the pressure of chasing a top-four spot.
Victory for the Gunners would have moved them above Tottenham into fourth with one game remaining, but they were second best at St James' Park.
"We wanted to have a big game but it didn't happen," Xhaka told BBC Sport.
"People speak always about leaders. We're not playing tennis, we're playing football. If someone is not ready for this pressure, stay at home.
"You can't come here and play like this. We looked very bad today. The game plan was totally different. We played a totally different game.
"They were running us over from the first minute to the 96th. When you play like this, you don't deserve to play in the Champions League.
"The thing is the pressure. If you can't handle the pressure, it ends like today. It looks like we can't do something against the pressure."

Ben White's own goal gave Newcastle the lead early in the second half before Bruno Guimaraes added a deserved second late on.
The result means Arsenal must beat Everton at home on Sunday (16:00 BST) and hope Tottenham - two points ahead and with a much better goal difference - lose at relegated Norwich.
"If Tottenham lose and we win, you never know in football," added Xhaka.
"We have to hope. Before the game everything was in our hands. It's a totally different game now."
'They were 100 times better than us'
The defeat was the Gunners' sixth in 11 Premier League games - coming four days after they lost 3-0 at Tottenham - and boss Mikel Arteta accepted Newcastle were better than his side in every department.
"Newcastle deserved to win by a mile," he said. "It's a really difficult one to accept.
"We have to cope with those nights [including the defeat by Spurs] and we didn't cope with those nights.
"Newcastle were 100 times better than us. In every department, you have to earn the right to play and we didn't do it.
"We have to put our head down and accept the performance was nowhere near the standard required for the Champions League.
"I am incredibly disappointed. It's a very painful one. It was in our hands and today it's not in our hands. We have to beat Everton and wait for Norwich to beat Spurs. There's always a tiny chance in football.
"From Tuesday, we'll prepare for Everton. It's still mathematically possible."
'Newcastle are a massive club with massive ambitions'Newcastle boss Eddie Howe has transformed Newcastle since taking charge in November last year
After the final whistle there were scenes of jubilation in the St James' Park stands, which remained full as supporters stayed behind to applaud the Newcastle players and coaching staff on their lap of honour.
It is an incredible turnaround for a side who were in the relegation zone when the Saudi Arabian-backed £305m takeover was completed on 7 October.
Signings made in the January transfer window have certainly helped, but manager Eddie Howe has also transformed the performances of several players he inherited.
"It's been a brilliant thing to be part of [Newcastle's form over the second half of the season]," Howe told Sky Sports. "We've done it through team spirit and unity.
"We'll remain very calm in this moment because it's a brilliant win but that's all it is. We have to work to improve in the summer.
"We're a massive club with big ambitions but my job is to focus on how we do it rather than talk."
