Jose Mourinho claims Arsenal are back in the race for the Barclays Premier League title after Chelsea were held 1-1 by Southampton . Arsenal beat West Ham 3-0 on Saturday and Arsene Wenger ’ s side , who have not won the league since 2004 , are now seven points behind Chelsea . Manchester City were beaten at Burnley 1-0 and Chelsea could only draw at Stamford Bridge . Jose Mourinho has admitted that Arsenal have joined Chelsea and Manchester City in the title race . The Blues struggled to break down Southampton despite Diego Costa 's first-half opener at Stamford Bridge . Arsenal saw off the threat of West Ham at the Emirates Stadium on Saturday with an impressive 3-0 win . Mourinho said : ‘ Of course Arsenal are in it . They are seven points behind Chelsea , but have one less match to play than Chelsea . ‘ Both City and Arsenal are in the title race . It depends on the momentum for Arsenal - the 3-1 defeat against Monaco or the 3-0 defeat against West Ham ? ‘ So the danger is always there . But I keep saying , we are there . If someone had told me in August that , at the end of March , we 'd be six points in front with a match in hand , I 'd have signed for that immediately . ‘ There are two perspectives . One perspective is a draw at home to Southampton is not a good result . For me , that perspective is very acceptable . ‘ The second perspective is we had a lead of five points from second , and now it 's six points with one less match to play. ’ Mourinho believed a wrongly-awarded penalty denied his side an eight-point lead over Manchester City at the top of the league . The Portuguese coach was fined £25,000 for saying there was a 'clear campaign ' against his side after Cesc Fabregas was denied a penalty and booked for diving instead in the December 28 draw at St Mary 's . Mourinho says that Arsenal are a danger to Chelsea , although he is happy with his current strong position . On Sunday Mourinho was frustrated Nemanja Matic was penalised - allowing Dusan Tadic to score from the spot and cancel out Diego Costa 's first Premier League goal for almost two months - while Branislav Ivanovic was not awarded a spot kick at the other end . ' I 'm happy with the situation . I 'm happy with the six-point lead , but I 'm not happy with the result , ' Mourinho said . 'If you remember our two matches against Southampton : in one game , one penalty that is not a penalty and in another game a penalty that was not given . You are speaking about six points transformed into two points . ' Mike Dean ( right ) gave Southampton the penalty for their equaliser , Mourinho said that it 'is not a penalty ' Thibaut Courtois could not keep out Dusan Tadic 's spot-kick and the playmaker secured a point for Saints . Mourinho was clearly upset with the penalty decisions , but bit his tongue on this occasion . He said : 'My opinion is not important . Important is Mr Mike Dean ( the referee ) . 'His decision was a penalty and his decision was no penalty on Ivanovic . ' Ivanovic may have been clipped by Tadic , but fell theatrically , dissuading Dean from pointing to the spot . Nemanja Matic brought down Saido Mane for Southampton 's equaliser but Mourinho was clearly upset . Branislav Ivanovic went down in search of a penalty but Dean did not give the desired spot-kick . Asked about the fall , Mourinho deferred to his media officer sitting alongside , saying : 'You have to control me , if not ... ' Mourinho was told television pundit Graeme Souness - with whom he had a public exchange of views this week after the Scot criticised Chelsea 's conduct in the Champions League exit to Paris St Germain - thought Matic had conceded a penalty . 'Graeme Souness says also that it 's more a reason to criticise a player who asks for a yellow card than a player who kicks somebody in the chest , ' Mourinho added . ' I went to Sky and they told me their pundits said it 's a penalty . I went to BBC and they told me it 's not a penalty . I went to the radios and they told me it 's not a penalty . Mourinho was told television pundit Graeme Souness thought Matic had conceded a penalty , and responded . Mourinho said that pundits 'win every game ' due to their position of being critical but exempt from criticism . 'Pundits are paid to wear my suit , but I 'm not paid to wear their suit or to comment on their comments . 'If one day I become a pundit , I will wear a manager 's suit . I will win every game , because pundits win every game , and then I can be critical and I can be phenomenal like they are . ' Matic was replaced by Ramires soon after a second-half foul on Sadio Mane which could have seen him booked for a second time - after his initial yellow when giving away the penalty - and sent off for a second successive Premier League game . 'When that penalty is given you have to believe that the second yellow card can come , ' said Mourinho . Matic was substituted for Ramires in the second half but could have seen a second yellow card for one foul . VIDEO Arsenal still not in title race - Wenger .
