When Arsenal spent £100m to sign West Ham midfielder Declan Rice last summer there was a suggestion in some camps that the Gunners had overpaid.
But those voices have quietened as the England international, with some brilliant performances in a more attacking position, has helped fire Arsenal to the top of the table with 10 games to go.
Maybe his biggest test yet will come on Sunday when they visit title rivals Manchester City, who also tried to sign Rice last summer and had a bid of £90m rejected.
The Gunners may be top of the Premier League - but they were in the same position after 28 games last season and fell away - so will Rice help them get over the line?
