Mauricio Pochettino says the uncertainty surrounding the futures of members of his Tottenham squad is not a reason for his side's inconsistent start to the season.
Danny Rose, Toby Alderweireld and Christian Eriksen appeared certain to leave north London during the transfer window, while Jan Vertonghen did not feature in Tottenham's opening three games of the season.
Last season's Champions League finalists ended a three-match winless run by beating Southampton with 10 men after Serge Aurier's sending off in the Premier League at the weekend.
The result eased pressure on the Spurs boss after consecutive defeats to Colchester and Leicester.
Harry Kane exclusively told Sky Sports that speculation hanging over various players has had an effect upon Tottenham's form at the beginning of the 2019/20 campaign.
However, speaking ahead of Spurs' second Champions League game of the season against Bayern Munich, his manager Pochettino insisted that the unsettled futures of players in Tottenham's squad cannot constitute a legitimate reason for the outcome of their games.
"When the transfer window closed I was clear that the players have a commitment to give their best," the Spurs boss explained.
"I didn't talk after that to say we had different injuries or that we were effected after Colchester because the team was not thinking.
"It wasn't the best start, it is now my sixth season here and it is always the same, different things happen in summer.
"There is no doubt the players are very committed, with a one-year contract or a five-year contract.
"That is not a point to discuss and that is not a reason for the team to have good or bad results."
'Bayern are always contenders'
Lucas Moura and Harry Kane's first-half strikes were cancelled out by Daniel Podence and Mathieu Valbuena as Spurs threw away a two-goal lead to draw their Champions League Group B opener away to Olympiakos on September 18.
Bayern Munich, meanwhile, earned a comfortable 3-0 victory at the Allianz Arena against Red Star Belgrade, through goals from Kingsley Coman, Robert Lewandowski and Thomas Muller.
The two sides last met in the Audi Cup final during pre-season, the game finishing 6-5 on penalties to Pochettino's Spurs after a 2-2 draw in normal time.
Bayern travel to north London on the back of an eight-match unbeaten run at the start of the 2019/20 campaign.
Niko Kovac's team, who were knocked out of last year's Champions League by eventual victors Liverpool in the round of 16, have not lost in their last nine European matches away from home.
"In the history of the Champions League they are a club that every season try to prepare themselves to try and win the competition," Pochettino added.
"It is a great club with great players and great coaching staff.
"It is a historic club which can be one of the contenders to win the Champions League."
Vertonghen open to Spurs extension
With the defender having under one year left on his current deal, Vertonghen addressed questions over his future prior to Spurs' clash with Bayern.
The Belgium international admitted he remains open to the prospect of Tottenham opening talks over extending his stay in north London.
He said: "I would prefer not to go too deep into that [contract situation] but there is always some movement.
"I am very ambitious, I feel like I have a couple of good years left in me. I hope I can help the team."
"I'm very aware of my age. I feel fairly young. It doesn't distract me.
"I want to play as many games as possible. I'm very ambitious and I feel I've got a few good years left at the top level."
The 32-year-old maintains that Tottenham have the ability to improve their form at the start of the season, with the Champions League group stages now fully underway.
"Maybe the results didn't come our way but they were tough away games and you always have to see how you bounce back from that."
Team news
All players were present in training on Monday bar long-term absentees Giovani Lo Celso (hip) and Ryan Sessegnon (hamstring), prior to their midweek clash with the current Bundesliga leaders.
Both players are undergoing rehabilitation but are not expected to return to contention before the end of October.
The other game in Group B sees Olympiakos travel to the Rajko Mitic Stadium to face Red Star Belgrade on Tuesday.
