• City agree £65m deal with Everton for Senegal winger

• Richarlison to stay at Spurs, who agree Mudryk loan

Manchester City are poised to bolster their attack by buying Everton’s Iliman Ndiaye for up to £65m and have opened talks with Chelsea over a deal to sign Enzo Fernández.

City’s hijack of Tottenham’s deal for Ndiaye came after their attempts to sign Liverpool’s Cody Gakpo broke down. The Senegal international is poised to undergo a medical after a fee of £60m plus £5m in add-ons was agreed with Everton, who have little time to find a replacement for one of their most important players before the transfer window shuts on Tuesday night.

In the fullness of time Chelsea’s surrender against Brighton in April may be seen as the turning point. The humiliation accelerated Liam ­Rosenior’s demise and forced the Stamford Bridge hierarchy into a ­reckoning leading to the appointment of Xabi Alonso, a shift in ­transfer ­strategy, the birth of the JP Morgan front three and the end of ­Robert Sánchez’s time in goal.

For now, though, the argument that Emiliano Martínez is the final piece in the jigsaw seems a touch ­premature. With seven goals scored and five conceded while winning their first two league games, it is not hard to see where Chelsea need to improve in order to sustain a title challenge. They have to be savvier when ahead, and although the good has so far outweighed the bad Alonso could do with his side not dropping their guard when they have the ­opposition on the ropes.

Carlo Cudicini was a very good goalkeeper. However, José Mourinho was ruthless when he became Chelsea manager in 2004. Very good was not good enough. Mourinho wanted the best and one of the main factors behind the Portuguese winning the Premier League during his first season in charge was the decision to replace Cudicini with Petr Cech.

There is an old line about a great goalkeeper being worth 15 points a season. It is not for nothing, for instance, that Brian Clough regarded Peter Shilton as one of his most important signings at Nottingham Forest. Shilton was key when Forest defied the odds by winning the Division One title in 1978 and there are plenty of other examples of promising teams taking the next step only after buying a top No 1.

All who attend the Rayan Cherki show know the ticket comes with a guarantee of entertainment. Enzo Maresca, a manager famed for his obsessive positional control, does not need to put limits on the Manchester City wizard. Cherki has to feel free and he was at his creative best against Crystal Palace, who were in this game before City’s creative heartbeat took it away from them in the second half.

It has been a fine start to the former Lyon player’s second year in England. Cherki was inspired against Bournemouth last week, coming off the bench to spark City’s fightback from 1-0 down with two assists, and this was better. The Frenchman scored twice and the first, a little prod with the outside of his left foot after a mazy run, left you wondering if you have seen something like it before.
