Hello
With 11 of their players in the squad over the age of 30, and a new World Cup cycle on the horizon, change is inevitable.
Martinez is taking a cautious approach towards a player who is key to Belgium’s chances in Qatar.
The FIFA World Cup is the biggest test for a footballer and greatness is attained based on the heroics in the showpiece.
Third-placed Chelsea, who had drawn with Everton and Wolverhampton Wanderers in their previous two games, are now level with second placed Liverpool on 41 points -- six behind leaders Manchester City.
Belgium, who were without Eden Hazard and Romelu Lukaku and only brought on Kevin De Bruyne in the second half, hit the woodwork three times.
Chelsea beat Aston Villa 3-0 for their 600th Premier League victory to move joint top of the standings alongside Manchester United.
Lukaku needed only 15 minutes to get off the mark for the Blues after his reported 97.5 million pounds transfer from Inter Milan.
The Belgium international is in line to feature against Arsenal in the Premier League on Sunday.
A Chelsea statement did not mention the agreed transfer fee, but media reports say the deal is worth a club record 97.5 million pounds ($134.7 million).
Belgium were among the favourites for the tournament, having spent more than 1,000 days at the head of the FIFA rankings.
