Coventry boss Frank Lampard has said transfer fees in the Premier League have been an eye-opener for the Sky Blues, who will play their first top-flight game for 25 years on Friday. Striker Sidiki Cherif became the club's latest summer signing on Wednesday after joining from Fenerbahce to push the Sky Blues spending to around £130m this summer. "One of the interesting things between being a player and transitioning into a manager is that you learn about the other side of the game, as in agents, transfer fees," said the former England midfielder.
