Petr Cech says Arsenal team-mates Mesut Ozil and Alexis Sanchez need to be shown “how much we need them” as speculation regarding their respective futures rumbles on.
Both men are due to be out of contract in the summer of 2018 and are yet to commit to extended stays at Emirates Stadium.
Debate as to when they might sign has dragged on for some time now, with Ozil revealing that his decision hinges on Arsene Wenger remaining in the Gunners dugout.
Alexis has also hinted that he would be prepared to put pen to paper, but talk of big-money offers from China refuse to go away.
Cech believes it is now up to those already tied to the club on a long-term basis to convince the key men to stay put, urging everyone connected with Arsenal to display ambition.
“I think for us it is important to show them how much we need them in the team and to show them how much we want to win,” he told the Evening Standard.
“Then obviously it will make their decision easier. If they see that we are competitive, everybody is ready to win things together and they know how important they are for our team, then this will make their decision easier.”
While much of the attention before and during the current transfer window has focused on possible outgoings at Arsenal, there is still plenty of time for fresh faces to be brought on board.
Wenger, though, has admitted of late that he is unlikely to enter a tricky mid-season market.
He said: “I believe it's completely against the spirit of what a football club should be.
“Once you are on the train at the start of a season, you stay on the train until the end of the season. I personally don't think that it is right.”
Cech believes Arsenal already boast a healthy strength in depth and will have no complaints if Wenger decides to follow his recent recruitment trend and steer clear of January additions.
He added: “On Saturday [against Swansea] we were missing players due to injury and so they are all basically close to fitness and back to the squad, apart from Santi [Cazorla], who will need a little bit more time.
“If everyone is fit then we have a strong squad. So this is probably why the boss said what he said. It is his decision. We concentrate on our game and then we train. If he brings in a player or not, that is his decision.”
