11 6. Right midfield: Xherdan Shaqiri (Stoke City) – When the Potters announced the £12m signing of Champions League winner Shaqiri from Inter Milan, the Premier League was shocked and a little excited. With a point to prove in England, the 24-year-old was expected to bring new attacking life to the Britannia Stadium. It hasnt gone to plan for the winger, though, with just one assist in 11 appearances. He has been bright in the final third, but has sadly left much to be desired. 4. Centre back: John Terry (Chelsea) – Terry played every minute of Chelseas 2014-15 title-winning campaign, the first player for the Blues to ever do so in the Premier League and, despite his age, many expected the Stamford Bridge icon to repeat his top form when the reigning champions set out to defend their crown. Over the past four months, this has been far from the case, with the centre back looking out of his depth in what has become a highly vulnerable Chelsea defence. Sadly, his influence in the capital looks to be thinning. 7. Centre midfield: Cesc Fabregas (Chelsea) – Fabregas almost broke the Premier Leagues assist record last season, but what was just as noticeable if not more so was his drop in form in the second half of Chelseas title-winning campaign. Jose Mourinho will have been hopeful that the summer break refreshed the Spaniard, but it seems to have had no such effect, leaving many wondering, is Fabregas finished at the very top level? 11 11 1. Goalkeeper: Lukasz Fabianski (Swansea City) – Fabianski was in outstanding form last season, recording the second highest number of Premier League clean sheets with 12. The Poland international, however, has failed to convince this time around, making a number of errors, and his confidence looks to have taken a worrying hit. 11 11 11 5. Left back: Patrick van Aanholt (Sunderland) – Van Aanholt was one of the Black Cats worst performers at the beginning of the season, with player after player breezing past him on the left wing. While the arrival of Sam Allardyce has seen his form improve significantly, he remains a considerable weak link for Sunderland, making it little wonder that Chelsea werent convinced by his potential as a youngster. 9. Left midfield: Memphis Depay (Manchester United) – The Netherlands international waltzed into Manchester with such swagger that supporters must have felt that a special player had been signed. His performances have been far from special to date, however, with Van Gaal opting to drop the winger to the bench after a miserable start to his United career. He has returned to the starting line up recently, but Old Trafford is yet to be wowed by their £31million man. Time is on his side, though. 11 With the festive period approaching, we’ve now seen enough action to fairly determine who has been performing to – and in some cases above – the standard expected and who has much to prove.At the end of October, talkSPORT put together a team of the season, and now we’ve taken a look at the most disappointing XI of the 2015-16 campaign so far.Some may be wondering, surely this line up must be made up entirely of Chelsea players?To find out the XI that have disappointed the most so far this season click the yellow arrow above, right. 10. Striker: Diego Costa (Chelsea) – Costa took no time at all to adapt to Englands top flight after his arrival last summer, but he looks a shadow of his former self this season. With his relationship with Jose Mourinho being called into question following the strikers bib-throwing tantrum at the weekend, he is becoming a growing problem in south west London. 11 8. Centre midfield: Moussa Sissoko (Newcastle United) – With the France international repeatedly speaking of his desire to eventually play in the Champions League and revealing that the Magpies did everything to keep me in the summer, great things were expected of his performances this term. Sissoko, though, has been one of Steven McClarens poorest performers, offering very little in midfield. There cant be many if any Champions League clubs lining up for his signature. 11 3. Centre back: Fabricio Coloccini (Newcastle United) – The form of Coloccini perhaps hasnt been a surprise to many; what has been a disappointment, however, is his attitude on the field as the Magpies struggle at the foot of the table. With reports of a training ground row between the centre back and manager Steve McClaren, it may only be a matter of time before the Argentine is stripped of the captains armband. 11 2. Right back: Branislav Ivanovic (Chelsea) – Over the past few seasons, Ivanovic has been one of Chelseas most consistent performers, with few attackers getting the better of him. However, the Serb has been in shocking form this season, so much so that supporters were delighted when he was ruled out through injury at the beginning of October. He made his return to the line up against Norwich and will need to seriously improve, particularly with his contract expiring in the summer. 11 11. Striker: Wayne Rooney (Manchester United) – Since scoring 27 goals in the 2011-12 season, the Red Devils captain has been on the decline. Most worrying of all has been his form under Louis van Gaal, which is showing few signs of improving, despite being handed the captains armband. With Robin van Persie and Javier Hernandez leaving in the summer, Rooney was expected to step up, but his Premier League career really could be coming to an unsavoury end, with the Old Trafford faithful having been open in their desire for the England international to be dropped from the line up.
