The chances of Nicolas Jackson leaving Chelsea this summer are growing, according to The Athletic.

Many clubs in the Premier League and abroad consider Jackson as a viable alternative if they do not land their top striker target.

Manchester United or Newcastle could therefore pursue him, depending on which of them misses out on Benjamin Sesko.

Aston Villa have also been linked with the Senegal international.

Jackson has scored 30 goals in 81 games for Chelsea, who are thought to want at least £80million to sell him.
