Mohamed Salah - £13m
Unsurprisingly Mohamed Salah tops the most valuable list going into the 18/19 season. He scored a massive 303 points last term and if you didn't have him in your team the chances are you weren't near the top of your league. The Egyptian topped the goalscoring charts with 32 goals and added an extra 12 assists to go along with it. At £13m he'll take a massive chunk of your budget and it could be a gamble.
He suffered an injury in Champions League final which ruled him out of most of Egypt's World Cup campaign. This will mean, unlike a lot of players, he'll be well rested and come back strong this season. With plenty of time to get over his shoulder injury he should be back to his best. Is he just a one season wonder? who knows, but with Jurgen Klopp's attacking style of play he'll get chances to score this season.
Harry Kane - £12.5m
Harry Kane, the one season wonder, has now scored 20+ Premier League goals in four consecutive seasons. He is now regarded as one of, if not the, best striker in the world. He comes back to England after a long campaign with the national teaming, finishing fourth in the World Cup and claiming the golden boot along the way. Scoring 217 points last season he finished third on points overall.
After such a long campaign in Russia he may be rested for the first few games for Tottenham. The striker, despite still managing to score a huge number of goals each season, has never managed to score in the month of August. Do you gamble that he finally breaks that curse and put him in from the start? or have a plan to get him in during the season when he finally gets going but he'll be a must have come the end of the season.
