Manchester City manager Manuel Pellegrini says he's 'very worried' about the club's upcoming run of fixtures.
The Chilean says he may have to field a youthful team against Chelsea in the 5th round of the FA Cup.
The fixture is scheduled for Sunday 21st February, one day before the squad fly out to Ukraine for their Champions League last 16 tie with Dynamo Kiev.
Pep Guardiola says he is "like a woman" and will be able to juggle his current role at Bayern Munich and preparations for life at Manchester City from the summer.
City confirmed Guardiola's appointment on a three-year contract on Monday, ending months of speculation over where his next destination would be with Chelsea and Manchester United also linked with him.
The Catalan, who said on Friday that the first contact with City came "in May or June", faces the challenge of ensuring his final season at Bayern ends with success on as many fronts as possible while ensuring he hits the ground running at the Etihad Stadium in the summer.
Asked how he would cope with that, he told reporters at a press conference: "I am like a woman, I can control both situations. I can think of both situations, so it's no problem for me."
The dream scenario of rounding off his Bayern reign with a Champions League, Bundesliga and DFB-Pokal treble is still achievable, and Guardiola insisted his focus is still very much on his work in Germany.
"I had my first talks with (Manchester City) in May or June," he said. "When I am in England, I will say more about it.
"If people don't trust me, then I can't change that. I know this is new for Bayern Munich - a coach has never left them before, it has always been them getting rid of their coach.
"But I will be focusing on the team until my final day here, giving my best to the very last minute."
Forget any moves for players, as the biggest story of transfer deadline day is Pep Guardiola's move to Manchester City.
Moments after City's current boss Manuel Pellegrini made the shock announcement at his pre match press conference that he'll be leaving, the club confirmed that the Spaniard will be the man replacing him in the summer.

Manuel Pellegrini says Joe Hart will not be the first choice goalkeeper for Manchester City in domestic cup competitions this season.
The City and England number one is being rested for a second game after starting on the bench against Everton in their League Cup semi final first leg in mid week.
Willy Callabero will start in goal once again for City when they take on Norwich in their FA Cup third round tie at Carrow Road on Saturday.
However, Pellegrini says Hart will come back into the first team for his side's Premier League game with Everton on Wednesday.

Manuel Pellegrini has refused to discuss fresh rumours linking Manchester City with Lionel Messi.
After successive defeats, City boss Pellegrini insists Saturday's clash with Southampton is his priority, not fuelling speculation the club are preparing to make an audacious £800,000-per-week offer for the Barcelona superstar.
And he will have to make do without Joe Hart for that game, after confirming the England goalkeeper will be out for around 10 days with a hamstring injury.
On the positive side, David Silva and Wilfried Bony are available again as City look to bounce back from last week's Barclays Premier League mauling by Liverpool and Wednesday's Champions League loss at Juventus.
Asked about the Messi speculation at his latest press conference, Pellegrini said: "I don't talk about rumours. I think every manager in the world would like Lionel Messi."
When pressed further, Pellegrini - who was similarly reluctant to talk about reports linking Pep Guardiola with his job - said simply: "I think we must win against Southampton."
City slipped to third after their 4-1 hammering by Liverpool but with top two Leicester and Manchester United playing each other, they have a chance to make up ground this weekend.
The loss of Hart, who has been in fine form this season, is undoubtedly a blow but Pellegrini has confidence in his replacement Willy Caballero.
Pellegrini said: "I think he will be around 10 days out. Fortunately it is not a very serious injury but it is a muscle injury so it is important for him to recover well.
"But I never complain about players who are injured. That is why we have a squad. We lost Joe in a very good moment but it is what happens. I trust a lot in Willy Caballero. I am sure he will have a good performance in these games."
City have been troubled greatly by injuries in recent weeks with Hart joining captain Vincent Kompany, Eliaquim Mangala, Pablo Zabaleta and Samir Nasri on the sidelines.
But the return of Silva provides a big lift after a nine-game absence with an ankle problem while the availability of Bony increases attacking options at a time when Sergio Aguero still lacks match-sharpness.
Pellegrini said: "David is a very important player, the same as Kun - one of the players that is very difficult to replace. I hope both of them can recover."
With a 0-0 draw at Aston Villa earlier this month, City have actually gone three games without a win but Pellegrini is not overly concerned about form yet.
He said: "Maybe one defeat in this club is a crisis for this club, in the media. Of course you worry when you don't win two games in a row but if you take an overall view I think we are having a very good season."
Southampton are likely to provide another strong test having not yet lost away from home in the Premier :League this season.
Pellegrini said: "In Premier League you never know which team will win against the other. You see Liverpool come here and beat us but Crystal Palace went to Liverpool and beat them, and after that Sunderland beat Crystal Palace.
"Southampton are having a good season. They have good players and we need to play in a high performance if we want to win."
The absence of Hart means third-choice Richard Wright, the 38-year-old former England international, will be on the City bench. He last played in the top flight for Everton nine years ago and has not played a competitive game at any level since appearing for Ipswich in 2011.
