Paris St Germain produced a performance with coach Luis Enrique's stamp all over it on Tuesday as they eked out a slender 1-0 advantage over Arsenal to take back home for the second leg of their Champions League semi-final.

PSG boss Luis Enrique was thrilled with his side’s performance in London but admitted his star forward will now be a doubt for the second leg in Paris next week. Enrique said in his post-match press conference: ‘I don’t know anything. The medical tests will take place tomorrow.

Arsenal beat PSG 2-0 earlier this season when the two sides met at Emirates Stadium in the league phase of the Champions League. The two clubs meet again in the first leg of their semi-final and Enrique insists his side have made huge strides since then.
