Jose Mourinho has publicly challenged William Gallas to explain why he has yet to play for Chelsea this season as the Blues coach continued his tough stance with the unhappy left-back.
Gallas missed the club's pre-season training camp in the United States but despite returning to full training, the defender has yet to figure for Chelsea.
The Frenchman was recently the subject of a bid from Chelsea's London rivals Arsenal, possibly as part of a deal which would pave the way for Ashley Cole to move in the other direction.
But a move to the Emirates Stadium now looks increasingly unlikely as the transfer window deadline approaches and Mourinho has urged the player and his agent to organise a press conference and explain why he is not playing.
Asked what the latest position with Gallas was, Mourinho said: 'The best thing to do is to ask him. People should talk to his agent and try to have a press conference with Gallas.
'There are a lot of answers but answers he should be the one to give. It is not that I don't want to tell but I shouldn't be the one to say things that he should tell. This situation deserves a press conference with the player.'
Mourinho's comments followed a typically abrasive response to more criticism of his players.
Chelsea slumped to a shock defeat against Middlesbrough last week but recovered to earn their second win of the season at Blackburn on Sunday.
But instead of basking in quiet satisfaction, Mourinho found himself having to fend off accusations that his side did not give Boro's players enough respect and that England captain John Terry dived to win their second-half penalty at Ewood Park.
Middlesbrough goalkeeper Mark Schwarzer felt that Chelsea did not acknowledge Boro's 2-1 victory last Wednesday night in an appropriate manner but Mourinho denied his claims and advised him to enjoy the moment instead of making 'stupid' remarks
Mourinho said: 'In football it is very difficult for the big people to lose matches but it is also very difficult for small people to win big matches.
'When you win and you are not used to winning big matches, you have also to behave.
'(Schwarzer) is a very good `keeper and because of that I don't believe he has vision problems.
'I don't believe because he is a good `keeper that he didn't see Chelsea players exchanging shirts with Middlesbrough players.
'I don't believe he didn't see the Chelsea manager waiting for Middlesbrough players at the end of the game to congratulate them.
'I don't understand what he is saying. It is better to enjoy the moment he beat Chelsea and don't say stupid things, because he won a good game.'
Mourinho's comment was underpinned by a Chelsea statement which questioned the goalkeeper's motives and explained why they had waited before issuing a response.
The statement read: 'The comments from the Middlesbrough goalkeeper are complete nonsense and totally ignore the facts on the night.
'Several Chelsea players swapped shirts with Middlesbrough players after the whistle and Jose Mourinho stood by the side of the pitch after the Chelsea team had already gone to the dressing room and shook the hands of most, if not all, the Middlesbrough players.
'One has to question Schwarzer's motives for coming out with this unwarranted attack on our players and manager given they are not borne out by the clear facts.
'We delayed our response to this because we had an important match against Blackburn and we did not want this issue clouding the build-up to the game, but we cannot allow this attack to go unchallenged.'
Meanwhile Mourinho was forced to respond to accusations from Rovers manager Mark Hughes after he called Terry's integrity into question over the award of Chelsea's penalty.
Hughes said: 'The penalty decision was a big decision in the game that the referee needs to get right, and he hasn't.
'John Terry is aware that (Blackburn debutant Andre) Ooijer is closely marking him, he knows that the referee is looking at him and decides to collapse his knees and fall in a heap.'
But Mourinho dismissed his counterpart's claims by handing out a history lesson to Hughes.
The Chelsea coach said: 'If Mark Hughes wants to speak about penalties, he should speak about three penalty decisions last season which he never spoke about. Last season he was very happy with three decisions and he won the game here and went home happy.
'The rules are very clear. If a defender pushes or pulls or keeps contact for more than two or three seconds with an attacker, it is a penalty. For me the penalty was clear.'
