Mental strength

^{Chelsea have not dropped below first place this campaign}Chelsea have topped the Premier League table since day one, re-establishing their lead every time Manchester City have got to within breathing distance of them. While City have faltered at vital moments, Arsenal made a slow start and Manchester United have stuttered their way through the season, Chelsea have managed to come through sticky patches of form unscathed. The ability of Mourinho's team to grind out a result or find a vital late goal has been second to none. Chelsea have always bounced back from a bad result, never losing two games in succession in all competitions at any point during the season.
