Shearer believes that Watkins, a centre-forward, may be left out of important games, which could impact his career. For example, he was not included in the team for the big match against Paris Saint-Germain. This made him think that he might need to consider his options.
Even though Watkins didn't score against Fulham, Shearer feels that he's one of the best players in the league at making runs behind the defence. However, with two years left on his contract and approaching the age of 30, he will have to decide whether to sign a new deal or look for opportunities elsewhere.
Shearer also mentioned that there were interest from Arsenal in January, which might have been influenced by Watkins or his representatives. This could be a factor in his decision-making process.
