The 2017-18 season was built up to be an exciting season for the blue half of Merseyside and their supporters. Enriched by owner Farhad Moshiri, the club spent big in the summer to help with the loss of striker Romelu Lukaku. In the first six months of this term, the club has endured Ronald Koeman’s sacking, flirted around the relegation zone and crashed out of European football too.Sam Allardyce’s appointment was one ultimately met with concerns as many were skeptical around the club’s ambition as well as the long-term planning behind this move. Granted when ‘Big Sam’ arrived, results changed and confidence collectively improved for Everton – they propelled themselves away from the relegation in the short-term.However now, a run of seven matches without a win has put doubts back among experts and supporters alike as they still run the risk of being a club battling relegation now.Another lacklustre performace by Everton at home to West BromTeam selections, tactics and the playing style would have to questioned by the current manager and Allardyce does not seem to know the best way in which to utilise this Everton squad.With constant changes in central midfield, to the organisation of more attack-minded players, there has to be a genuine concern that even their own manager is unaware of the best way to play this current Everton crop.The club was always going to spend money during this current transfer window and thus far, they have added another £47m to their spending tally for the campaign. Arrivals of highly sought-after Turkish international Cenk Tosun and Arsenal’s forgotten man Theo Walcott are sure to boost their attacking options.Tosun, despite blanks against Tottenham and West Brom, looks encouraging. He will provide both power and technique to the Toffees’ frontline, having netted 41 goals in 96 appearances for Besiktas.As for Walcott, he has plenty of pace, precisely what Everton need, and created an assist against the Baggies on his debut this past weekend while proving both sharp and industrious.Walcott enjoyed a good debut display for his new employersThe biggest disappointment for Everton fans is their style of football. With the quality of players in their side, they should certainly be expecting the team to play better than they’re currently producing.Concerns will continue to grow further, especially when the manager is quoted as saying that they need to be more boring – it has been asked, can they get any more?Dominic Calvert-Lewin needs to start, as he’s been the one player who has really covered himself in glory this season and looks to be a threat to opposition defences whenever he plays.Tom Davies should be given the opportunity to develop a midfield pairing alongside Idrissa Gueye, while the possibility to play an attacking midfielder ahead of the duo, or a third central midfielder usually depends on the opposition and type of tactics that Allardyce opts for.Morgan Schneiderlin has struggled for form this term and as a result, the Frenchman’s place in the side is not justified at present. Three of their summer acquisitions have been ultimately poor thus far, with record signing Gylfi Sigurðsson and Wayne Rooney appearing unable to play in the same side.Davy Klaasen meanwhile, has not been given a fair chance to showcase his ability despite the level of criticism he has received since joining from Eredivisie g Ajax.?-On ability and each of their respective stages of their career Klassen is technically and creatively the best of the three, yet Sigurdsson really has to play as the club paid in an around 50 million for the Iceland international and Wayne Rooney is still relying on his name to merit his inclusion.These three players have been an issue since their summer arrivalsThis transfer window is a fantastic opportunity for Allardyce to address one of the biggest issues at the club and that is the current position at left back. Leighton Baines has been a fantastic servant for Everton but injuries are really playing a big part in his career now, so Everton need to find the next player to take over from the former England international.Currently the team has Cuco Martina playing in this position and despite a handful of decent performances, the former Southamption player is simply not good enough to be starting for the club in this position. The biggest confusion with the left back conundrum at the club is what has happened to the promising Brendan Galloway? Two seasons ago he was fantastic for the club during the absence of Leighton Baines, then two loan moves and the once proclaimed future England international has fallen off the radar.Everton needs to invest in a left back to improve this shaky back line which has in honestly has been poor the majority of this season. Links with Bristol City star left back Joe Bryan would look an unlikely move with his attachment to the club at this stage and given the excellent position Bristol City find themselves in. West Ham left back Aaron Cresswell has been another player of interest to Everton. The current West Ham player would be the ideal signing for the club especially with his crossing ability to service the new striker Tocun. Could Everton start a scramble for Manchester United left back Luke Shaw? The former Southampton man looks like he needs to move away from Old Trafford to regain his fitness and confidence, Everton could prove the ideal move for his future.Could Everton make a move for Luke Shaw this window?This transfer window could define the rest of the season for Allardyce, who might even be looking over his shoulder right now Marco Silva without a club. The Portuguese manager was Moshiri’s first choice to replace Ronald Koeman after his sacking and now with his availability, question marks might just be asked about the future of the former Bolton and West Ham manager. The club still has work to be done in this window, could they get a better central defender to replace the questionable Ashley Williams? Will they get that left back that would add balance to the Everton team, and might they add yet another attacker to their options?The squad needs trimmed down, and with some example players such as Morgan Schneiderlin under-performing, Sandro Ramirez falling out of favour, Michael Keane struggling to break back back into the team, Yannick Bolasie returning from injury but not looking anywhere near sharp, Oumar Niasse not considered a starter and Davy Klassen is not getting a look in, they are certainly viable ways for Everton to get players out the door as well.
