1) Victor Wanyama- The Celtic midfielder is only 22 and yet has experience of winning trophies and playing in the Champions League against European heavyweights such as Barcelona and Juventus. On the occasions I've watched him play for Celtic I've been very impressed. Technically skilled, disciplined and very good in the tackle. A good shield in front of the back four and would replace the midfield muscle of Fellaini as well as any other attainable options at least. He would cost around £10 million.
2) Keisuke Honda- an attacking midfielder or forward who scores goals and is vey technical and creative, as he has shown at the Confederations Cup playing for Japan, most notably against Italy in the 4-3 thriller. With his good balance, creative vision and technical ability, the experienced Japan international would complete a very good looking central midfield area for Everton alongside Gibson and Wanyama. The attacking threat of Fellaini would be replaced by Honda and the defensive midfield muscle and protection of the Belgian would be replaced by Wanyama. Honda would cost very little as his contract runs out in December.
3) Nathan Redmond. A young winger at Birmingham at the age of 19 and would be available for around £2m as Birmingham are in desperate need of cash. Very skillful, tricky and quite two-footed. He has an eye for goal from all sorts of ranges- poaching in the box or more long distance strikes from outside the area. He has received raved reviews including Birmingham's fans and has plenty of time to improve on his already impressive abilities. In case he decided to leave he also has the potential for a high re-sale value. He also has better technique and end product than Callum McManaman in my opinion so along with the cheaper price, is a more attractive proposition.
4) Andre-Pierre Gignac. The Marseille striker is 27, has experience of playing the Champions League and has been linked with Arsenal and Man Utd before. He is strong, good in the air, technically able and has made 13 appearances for France and could be available for around £10-12 million. The main position Everton need to strengthen as it stands is centre forward and Gignac could fit the bill. Him being supported by Honda could be a great partnership that could give Everton that extra edge in and around the opposition's penalty area. Too many times last season the Blues failed to kill off teams but if they signed these two they'd be more ruthless in front of goal than last season.
I believe these 4 signings, costing around £25- 28 million, would be a fantastic foursome that would make Everton genuine contenders for the top four. They were only 10 points away last season, largely thanks to failing to kill off teams in the bottom half and I think these signings would help prevent them from repeating that fault this coming season, as well as covering the loss of Fellaini. At he very least they'd be well placed the get a Europa League place.
